H110 in the 550D: Will it fit?

[jlarimore]

My current concern is heat. I haven't even touched overclocking the CPU (3970X) at all and I am getting load temps of ~75C. I am cooling with a Corsair H90 (as exhaust) and am definitely disappointed that I don't really have any room to overclock. I know that it's not ideal to exhaust through the radiator, but I am blowing a lot of air through my 550D, (4 140mm fans and 2 120mm fans) and I feel like the air flowing through the radiator should be cool enough no matter which direction it's headed.

 

First question is, is something wrong with my H90? This is my first watercooling experience and I am not absolutely sure everything is working properly. I think it's pumping, (the motherboard is at least reporting fan speed which I assume means it's pumping) but I cannot be sure. I have the radiator tubes running out the top of the radiator. Is that OK? Or will the pump not like that? Is the thermal paste that came on the H90 junk? Should I replace that with AS5?

 

So, I am considering trying to squeeze an H110 in my 550D case. From my rough measurements it's going to be a REALLY tight squeeze. (I know Corsair's official stance is that they won't promise that it'll fit in this case) I have about 25-30mm of space between the two Corsair 140mm fans mounted as exhaust at the top of the case and a pesky heatsink on the mobo. I need to find someone who can measure the radiator on the H110 to see if it will fit. Is it the same 25mm thickness as my H90? Is it thicker? I guess even if it doesn't fit with my existing fans, I could always find squatter fans?

Sorry to tell you brother but our hex cores put out a TON of heat. Very best case scenario is you get an extra 10°C knocked off. These things really do need custom water. I'm at a mere 1.3v 4.4v and I cap out at about 83°C on the hottestcost and my case has 5 140mm fans 2 side 120mm fans and push/pull on an h100i. II'd say even an h110 couldn't really handle over 1.3v if u already have a hot running chip. Like I do and seemingly you do. All these people saying they get 70°C max on an h100i at 1.4v 4.8ghz or whatever are either full of it or got a lucky chip that runs cooler (every CPU is different). Ram voltage helps a bit to tho. I undervolted my ram from 1.65v to 1.55v and runs very stable and dropped 4°C off my CPU temps.

Well, I'm glad to hear that at least what I am seeing is not totally abnormal and that I haven't done something completely stupid.

 

I am running my RAM at full speed 2133mhz 1.65v. So, maybe I'll back that down a bit and see if the CPU temps lower with it. Thanks for the tip.

Well your specs say u have 2400mhz ram. If your running 2133mhz u could try loading up the 2400mhz xmp profile then dropping the speed to 2133mhz and dropping voltage to around 1.55v. That way you'll have the looser timings of the 2400mhz but the 2133mhz speed. Should function well at a lower voltage. Then again mine r running at 1866mhz xmp profile which is stock 1.65v and I dropped to 1.5v but got an error after 5 runs of Linx on maximum ram, then I upped to 1.55v and ran 20 runs just fine. All I did was drop voltage so you may have some leeway to. Ram is a lot of trial and error when stepping away from the basic xmp setting. But at least they give you a good starting point.

I returned the 2400mhz RAM because people advised me that 2x32GB kits was unlikely to run stable. I got the 2133 RAM because the 64GB kit of 2400mhz RAM seemed to be discontinued. I need to update my specs.
