  1. This an update on the comment on noise. I did not connect the cooler fans correctly at first. The fans should be connected to the CPU fan 4-pins header. They are PWM fans and the can be controlled by the MB smart fan control if the MB has that feature. They fans are now running below 1000 rpm in normal operation and are very quiet. The water pump runs at constant 1500 rpm and can be connected to any fan header, 3 or 4 pins. There is no change to the CPU core temperatures at the lower fan speed. I am surprised that no one asked me about the fan connection so far. Originally, I connect the pump to the CPU 4-pins which was a waste because the pump rpm is not controllable. Now, my question about connecting 2 fans in parallel to one 4-pins header. Is the fan speed reading accurate? I have no concern about the actual cooling control because it keep the fan speed up and down according to the CPU temperature. Both the MB and Corsair LINK4 shows the fan rpm as 780. I suspect the fans are faster based on the noise I hear. None the less, I am even a happier Corsair owner now.
  2. Wow, the result is amazing. The cooling is fantastic. The temperatures of the Q9550 (quad) ranged from 24 to 38°C, in a 20°C basement room. It was measured at a moderate overclocking to 3.0 GHz, FSB @ 353. The setup is a little noisier than my Artic-Cooling heatpipe cooler due to one of the fan running at 1945 rpm, which I should not need. It should be much quieter when I lower the fan speed to 1300-1500. I have not figure out how to yet. Corsair Link 4 (2016 release) loads and runs under Windows 10 64 bits smoothly.
  3. The Asetek mounting kit is on order, but it won't arrive until next week. So I decide to do surgery on the Corsair hardware. You must have a LGA775 generic backplate. I expect almost any generic one will work. But you cannot modify the Corsair one coming with the H75 kit. The mounting slots on the metal bracket must be move inboard 1/8" each. I tried to drill it out, but it did not work. Corsair use good gauge hard metal for the bracket. It ruin the drill bit, even carbide ones, quickly. My Dremel with the thin cutting plate did the trick for me. It takes time and must be done carefully. Spark fiies, so wear work gloves. The result looks really ugly, but it allows me to mount the water pump head properly and securely on the 775 motherboard. Now, I am ready to put my desktop computer back together to test it. I have an Intel Core 2 Quad Q9550. The CPU temperature runs about 60-65°C with stock cooler. It drops to under 50°C with an Artic-Cooling Freezer 7 Pro. The case is a Lian Li VC-P1200 Plus. I am just curious to try liquid cooling. If it gets quieter and cooler, it is a bonus.
  4. Stealthgaming, thank you for all the posting. Unfortunately, in 2013, Corsair changed their pump mounting hardware for the Asetek made Hydro series completely that look very different from your mid 2015 posts. I have a LGA775 motherboard and found that the only way to install the H75 is to get the Asetek mounting kit. http://www.ebay.com/itm/Asetek-Liquid-Cooler-Intel-LGA775-Retention-Ring-Kit-/280938268278 Corsair will not sell you the original series mounting hardware anymore. I found all this out only after I purchased the Corsair H75 kit. While waiting for the Asetek mounting kit to arrive, I decide to do surgery on the Corsair hardware. 1.

The CPU temperature runs about 60-65°C with stock cooler. It drops to under 50°C with an Artic-Cooling Freezer 7 Pro. The case is a Lian Li VC-P1200 Plus. When I mounted the H75, the CPU temperature dropped to 24°C in a 20° basement office at normal CPU frequency of 2.83 GHz. I can easily overclock to 3.2 GHz whereas the CPU raised to 29°C. I cannot be happier. I can push the CPU to higher OC frequency, but will stay at 3.2 GHz for now. The H75 kit comes with 2 120mm PWM fans. I have 2 PWM header (4-pin type) on the Gigabyte motherboard (EP45-UD3R). The fans are somewhat noisy if running at full 1950 rpm. Using the MB smart fan control and 4-pin header, they are quite and at 900 and 1100 rpm at CPU and System2 header respectively. Raising the fans to higher rpm has little impact to the CPU temperature.
  5. Toasted, thank you for the link again. I went to the Asetek website and confirmed that they are the OEM manufacturer for the Corsair Hydro Series. Very interesting. The Asetek kit seems to be the only easy way to mount the post 2013 H75 to a LGA775 motherboard. I measure the slots on the pump mounting ring. They are too far out to match the 775 holes. There are plenty of rooms on the ring if you want to drill it out to fit the 775 holes.
  6. It is no longer available, unfortunately. Yes, I noticed that RAM GUY's reply is almost 3 years old. But Socket 775 is not quite dead yet.
  7. I just received a reply to my RMA enquiring about the old 775 compatible mounting bracket. The Corsair support reply said that the 775 compatible mounting kit that RAM GUY suggested is no longer available. It seems to me that the H60/H80/H100 produced in early 2013 do support the LGA775 motherboard. The version 2 kits produced later that year drop the 775 support. I am surprised that Corsair drop the replacement parts support so quick.
  8. I have a Corsair Hydro H75 sitting on the bench waiting for a LGA775 solution. I would suspect it cannot cost Corsair more than 25 cents to include a second backplate for the 775. Now, the end user has to pay an extra $10? It does not make sense no matter how small the 775 customer base is. BTW, I have no reason to upgrade because the core 2 Quad Q9550 does not take a back seat to most i5 CPU and is very stable OC. I am waiting for a reply from Corsair support. Thank you for the Asetek item link.
  9. Corsair Dustin and RAM GUY said that Corsair no longer supports LGA775 socket. I understand that. I Goggled "Corsair liquid cooling Socket 775" and found 2 reviews of the Corsair H75 in early 2014. Thinking it is new enough before I ordered the cooling kit. Corsair Hydro Series H75 Liquid CPU Cooler Review Corsair H75 CPU Cooler Review - Hardware Secrets Both review showed the H75 comes with a bracket backplate that supported LGA775 and showed picture of the backplate. I understand that Corsair can change its product any time. My question is whether I can order the old backplate as replacement part? What parts number do I use? If I will have to pay for it, how much?
