  1. Hi everyone ! I'm the possessor of a corsair hydro series h105 since may 2014, last week I've noticed a stain on my GPU, so I got the h105 out of my case and cleaned it a bit. I didn't liked what I saw, it looked like there was a little leak from the radiator itself. So now I'm scared to mount it again, what if it go crazy spitting coolant everywhere in my case ? Since the AIO was baught in 2014 my warranty may be ended and I don't want to loose my brand new GPU. So here's my question : does this looks like a leak for you guys ?
  2. Just a couple of days ago, I talked about the drawbacks of having a beastly dual-GPU system featuring a custom liquid cooling loop as well as my solution to the problem in the form of my new Carbide Series Air 240 build that I dubbed “Blues.” I believe largely in balance, not overkill, though there is something to be said for the joy of assembling by hand a massively powerful machine. Knowing that my performance target wasn’t 4K but 1080p (and occasionally 3x1080p) suggested that my existing system wasn’t worth the 600W of power it consumed under gaming load, not to mention the corresponding 600W of heat it has to dissipate into a room that enjoys Californian Indian summers. Using some of our newest hardware, I opted to build a machine that would run as quiet (if not quieter) than my existing system while retaining the required amount of performance – but with superior performance per watt. These are the specifications of the two systems, compared. My old system was named “Ted” and it’s been with me for a while in an almost comical number of permutations. TED BLUES CPU Intel Core i7-4790K @ 4.7 GHz, 1.31V Intel Core i7-4790K @ 4 GHz, 0.975V Memory Corsair Dominator Platinum 32GB DDR3-2400 10-12-12-32 1.65V Corsair Dominator Platinum 16GB DDR3-2400 10-12-12-32 1.65V Motherboard ASUS Maximus VI Formula (Z87) ASUS Z97I-PLUS (Z97) Graphics 2x EVGA GeForce GTX 780 3GB (980 MHz Core, 6 GHz GDDR5) AMD Radeon R9 290X 4GB (1 GHz Core, 5 GHz GDDR5) CPU Cooling Custom Loop Corsair Hydro Series H75 w/ SP120 LED Fan GPU Cooling Custom Loop Corsair Hydro Series HG10-A1 Corsair Hydro Series H105 w/ 2x SP120 LED Fan PSU Corsair AX860i Corsair HX750i Storage 4x Corsair Neutron GTX 480GB in RAID 0 3x Corsair Force LX 512GB in RAID 0 Enclosure Corsair Carbide Air 540 Corsair Carbide Air 240 You can see I didn’t make a lot of brutally unkind cuts. I maintain that 2400MHz is the sweet spot for memory on Haswell and Devil’s Canyon, so that was worth the modest increase in power consumption. The AMD Radeon R9 290X is by no means frugal with power, but it is an incredibly fast card; had the NVIDIA GeForce GTX 980 been available when this build was assembled, that would’ve been the more sensible choice. While Blues is obviously inferior in performance to Ted, nobody would really be “slumming it” by making the transition. So what do we save in power, and what do we sacrifice in performance? Note that these games were all tested at or near their highest settings; Metro: Last Light Redux was maxed out with SSAA but with Advanced PhysX disabled, while Tomb Raider was only run with 2xSSAA and TressFX enabled. What we see is that in our synthetic video encoding benchmark, for our ~15% reduction in CPU clock speed we lose ~13% of the performance. That’s not too bad. Games run the gamut; BioShock Infinite’s minimum frame rate doesn’t change drastically, and the average stays well above 60 fps. Tomb Raider’s minimum does drop below 60 fps, but the average is above, and the single R9 290X doesn’t suffer from the rendering artifacts with TressFX that the SLI’ed 780s do. Metro: Last Light Redux is the most unpleasant hit, but still stays well above 30 fps. Finally, F1 2013 doesn’t seem to have SLI functioning correctly, but it’s irrelevant: either system maintains over 60 fps. We can use the Corsair Link connectivity of our AX860i and HX750i power supplies to see how much power each of these systems is drawing, and that’s where the difference really lies. While Blues peaks at about 365W under its most taxing load, Ted is gunning all the way up to nearly 600W. Particularly alarming is the near doubling of power consumption under the x264 benchmark for an extremely modest increase in performance. This is the truth of overclocking: at a certain point, substantial amounts of power become necessary to hit higher and higher speed bins. Almost entirely across the board, though, Ted is drawing substantially more power than Blues does, and arguably a lot of that is wasted performance. Mapping performance per watt puts it all into a different perspective. Since all of our benchmarks are measured in frames per second, we can divide those results by the peak power drawn during the benchmark to come up with a rough idea of how efficiently each system is running. This isn’t the grand slam that the absolute power consumption is; performance per watt stays mostly level in every game but the odd duck F1 2013. CPU efficiency is vastly improved, though. The measure for success here is overall power consumption while maintaining acceptable performance levels, and on that front, Blues, is a victory. I’ll be mothballing Ted for a while and spending more time with Blues to see if the reduced performance is really worth writing about, but for now, this has been a fun exercise in seeing how we can make our systems more efficient. We have overclocking competitions and records, but I’d love to see users trying to hit performance targets while reducing power consumption as much as possible.
  3. Having a boss overclocked, dual-GPU, custom-liquid-cooled system is pretty fantastic. It’s quiet, fast, runs any games I throw at it…it’s hard to complain too much. From the outside (or at least outside California), there’s very little wrong with having something that beastly to play with. And indeed, it’s hard to complain. Except in the summer. Except when I need to work on it. Except… There are drawbacks. Power consumption is high, and that means the system has to dissipate a tremendous amount of heat. California is experiencing one of the hottest summers in history (to say nothing of our drought), and we’ve never had very low power bills. A system like mine is great right up until I run headlong into the drawbacks. In a bid to see if I could make my life easier, I decided to take advantage of some of our new products (one of which isn’t out just yet but will be very soon) and produce a leaner, more purpose-driven build. It still has to be quiet, it still has to deliver superior gaming performance at my home resolutions of 1920x1200 and 5760x1200, and it can’t feel like a substantial step down. At the same time, it has to draw a lot less power. Let me introduce you to Blues. In the interest of producing something smaller, easier to use, and still incredibly powerful, I opted to employ our new Carbide Series Air 240 enclosure. The Air 240 is particularly special because unlike many of our other cases, it wasn’t entirely planned. While we take tremendous care in all the products we develop, the Air 240 was something that we really wanted. Remember that the people designing Corsair products are die hard enthusiasts, honestly just a bunch of nerds that come to work every day and ask themselves what they want to see on the shelves. This case was a pet project, and it’s everything we hoped for. Call it cliché, but my favorite color combination continues to be the time tested black and blue. For me, that meant taking the black version of the Air 240 and then fitting it with a series of our new SP120 blue LED fans. But just because I opted to use efficient fans doesn’t mean I was guaranteed silence. For that, I needed to choose my components very carefully. The CPU is Intel’s Core i7-4790K based on the Devil’s Canyon version of their Haswell architecture. These chips are Intel’s top of the line, but rather than overclocking, I opted instead to lock the peak clock speed to a still speedy 4GHz, allowing me to drop the Vcore to just 0.975V. This keeps temperatures low, ensuring the SP120 LED fan on the Hydro Series H75 cooler never has to spin up. Attached to the CPU is 16GB of Dominator Platinum DDR3 running at 2400MHz CAS10 with blue Lightbar kits installed. 2400MHz is really the sweet spot for Haswell, and 16GB ensures I never run out of system memory. That hardware is all plugged into an ASUS Z97I-PLUS mini-ITX motherboard. The Z97I-PLUS has a fairly understated color scheme while being very feature rich. Of course the other part of the equation is gaming performance, and that’s where our new Hydro Series HG10 comes into play. I swapped out the noisy stock cooler of an AMD Radeon R9 290X for the HG10 and then attached our 240mm Hydro Series H105 CPU cooler to it. The result? R9 290X performance, always running at the full 1GHz on the GPU, without any of the noise. It’s quiet, and it’s fast. You can see that overall, the interior design of the Air 240 is pretty efficient. The hoses on the H75’s radiator do apply a little pressure against the memory slots, but everything does fit, and it looks surprisingly neat for a small form factor build. The remainder of the primary chamber is kept cool by three more blue SP120s, but with a total of six fans and only three fan headers on the motherboard, how on earth was I going to keep the noise down? Not pictured: cable management skills. I continued by employing an incredibly efficient HX750i power supply, a unit that has a fan that only needs to spin up under substantial stress. That HX750i, along with the six primary chamber fans, gets connected to our new Corsair Link Commander Mini. The Commander Mini’s improved hardware over the original Cooling Node allows for precise control of the six main fans, letting me run them all at their lowest speeds. Finally, you’ll see that I have a trio of 512GB Force LX SSDs handling storage duties, providing plenty of high speed storage for gaming and video editing. With this fairly robust system (in a fairly small footprint) on hand, the major test is whether or not it’s worth the reduced noise, heat, and power consumption. That’s something we’ll be looking at very soon, so stay tuned.
  4. If you were at PAX, then you already know we had a couple of incredibly beefy gaming systems with tri-monitor surround configurations set up there. Of course, if you weren’t, then the systems we had built up for head-to-head gaming might surprise you a little…especially since we couldn’t even announce what was running in them until August 29th. But that time has passed, and now we can show you our PAX Graphite 780T red and blue configurations. We knew in advance that Intel would be using PAX Prime as their opportunity to launch their new high end desktop platform, complete with Haswell-E processors, X99 chipset, and DDR4 support. It would have been frankly embarrassing if we showed up with anything less. That’s why we got these two bad boys ready to go. These two systems were almost identically configured with the components listed below: Processor Intel® Core i7 5960X Motherboard Asus® X99-DELUXE GPU 2x EVGA® GeForce GTX 780 ACX Superclocked Case Corsair Graphite Series 780T White PSU Corsair HX1000i Power Supply (Blue); Corsair AX1500i Power Supply (Red) Memory Corsair Vengeance LPX Black DDR4 2800MHz (4x4GB) Storage Corsair Neutron GTX 240GB Cooling Corsair Hydro Series H105 Additionally, we used red and blue sleeved cables along with red and blue SP120 and SP140 LED fans to contrast the systems against each other. You can see glamour shots of the two systems below. With eight fast cores, sixteen gigabytes of new DDR4 memory, and dual GeForce GTX 780s in SLI in each system, let’s just say we didn’t have much trouble running our games at the required 5760x1080 resolution that the trio of monitors plugged into each system called for. Here the blue/white system is in action at PAX Prime and barely breaking a sweat.
  5. There’s a curious split in the market: people are going bigger or smaller. Far be it for me to suggest people shouldn’t buy full ATX cases or larger; these cases provide ample space for multi-GPU configurations and the increased case volume can improve cooling. Likewise, half the fun of a mini-ITX build is seeing how much power you can cram into an enclosed space, something we experimented with when we did our “God Lives Underwater” build in the Obsidian Series 250D. The funny thing is that Micro-ATX is, at least in my opinion, really the sweet spot form factor. Four expansion slots (enough for two graphics cards), four DIMM slots, and typically just as fully featured as the bigger ATX boards. Our Obsidian Series 350D may be a bit bigger than most Micro-ATX enclosures, but it’s as fully-featured as they come, even including a fifth expansion slot specifically for multi-GPU configurations. And as it turns out, you can fit a ridiculous amount of power in it. To prove it, and to give our shiny new AX1500i 1500-watt power supply a good workout, we built arguably a pretty ridiculous system in the 350D. What may surprise you more than anything is that it works and works very well for a machine that has to dissipate up to 1.5kW of heat from a fairly small enclosure. As a last hurrah to the X79 platform before Haswell-E and X99 descend upon us later this year, we used the ASUS Rampage IV Gene as the basis of our system and then plugged in an Intel Core i7-3930K. The i7-4930K is readily available, but doesn’t enjoy the kind of overclocking headroom (or heat dissipation) of its predecessor. On top of that was 32GB (4x8GB) of DDR3-1866 Vengeance Pro memory, which when combined with Sandy Bridge-E’s quad-channel memory controller offers a staggering 50GB/sec of memory bandwidth to keep our hexacore processor fed. Storage was handled by a 480GB Corsair Neutron GTX SSD, gingerly mounted behind the 5.25” drive cage. Why, you ask? Because we had to remove the 3.5” and 2.5” drive cages to make room for our Hydro Series H105 CPU cooler, installed in the front of the case in a push-pull configuration with Quiet Edition SP120 fans. The 350D only has enough clearance at the top for an H100i or H110; the H105’s radiator is just a little too thick, to say nothing of trying to install push-pull fans as well. Of course, it’s also because we had to make room for two AMD Radeon R9 295X2 graphics cards. These monsters are rated for 500W apiece, but they can easily exceed that. That’s why it’s important to use a dedicated 8-pin PCIe cable for each power connector on the R9 295X2 instead of the traditional daisy-chained ones. Those cables are fine for any other graphics card, but AMD breaks the PCIe connector spec in a very big way with the R9 295X2, so dedicated cables are needed lest you melt the connectors. The radiators for the Radeons are mounted to the top and rear of the case; the H105 serves as an intake in the front, cooling the CPU before air flows through the two R9 295X2 radiators. This creates a pretty clear and directed air flow path, and the ambient internal temperature of the case itself becomes less relevant. Under load we’re looking at a rated TDP of about 1.2kW, but it’s very easy to exceed that. The CPU is overclocked to 4.4GHz with a commensurate bump in voltage to ~1.35V; 4.5GHz simply wasn’t stable at any voltage. Actual load figures were pushing very close to the AX1500i’s rated capacity, but the system ran surprisingly quietly all things considered, and thermals were perfectly fine. We had to run FurMark for an extended period of time to get the Radeons to start throttling. Seeing results like these makes it hard to fathom a system that the Obsidian Series 350D wouldn’t be able to handle with aplomb. If you want a mid-tower-sized system with full tower performance, this certainly seems to be the way to go.
  6. The Corsair Hydro Series H105, and its junior sibling the H75, use a different mounting method than many of our other liquid coolers. Here at Corsair Labs, we’ve produced a short video with step by step instructions on how to install the H105 in your system along with a brief list of cases we produce that are compatible with the H105.
