Mounting H60i/H80i/H100i on LGA775?

[keilau02]

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.

[keilau02]

Not really, but by all means go ahead and send the request and we'll send you the bracket that supports socket 775.

 

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.

[keilau02]

Do you have the H75?

 

If so, see;

It should work, but i cannot guarantee it. So it will be best to research more or possibly ask Asetek.

 

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.

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.

 

1. 
   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.

[keilau02]

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.

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.

I noticed when trying to mount the backplate for an H60i/H80i/H100i on an LGA775 board that it is impossible to mount it in its stock condition (without modifying it).

 

Is there some way in which I can utilize an H60i/H80i/H100i on an LGA775 platform, say for instance using the stock backplate from an H60/H80/H100 cooler?

 

Personally, I think it was a mistake for Corsair to eliminate the Intel LGA775 socket from the compatible sockets list for their Hydro "i" series coolers at this point in time, given that it is still in use by many PC builders, owners, enthusiasts, and overclockers. Really it's not that much of a stretch of the imagination that there might be some people out there who run LGA775 and say own an H50/H60/H70, or run air cooling but want to try liquid cooling, but want to upgrade to a newer H80i or H100i.

 

I know this thread is dated, but I have seen a lot of the 775 boards and CPUs coming up for sale, and thought this might be relevant. I bought a used Supermicro rack server on the cheap and pulled the mobo (Supermicro X7dBE+)that had two LGA 775 Intel 3ghz quad core Xeon processors on it. The reason I pulled it was because the CPUs had passive heat sinks cooled with three 80mm fans running at 6000rpm which made a ton of noise. I put the mobo into a Zalman MS800 case, with the idea of using two Corsair water coolers which I bought (H50). The H50s are flat on top, and just needed to be clamped to the CPUs. Since the Corsair H50s didn't have the LGA775 CPU hardware, I turned to the passive cooling blocks which came with the board. The blocks mount to this board by threaded holes in the 4 corners with #6 screws which perfectly lined up with the holes in the mobo. I took the CPU blocks and used a cutting wheel to cut off the block fins leaving only the rectangular bases. I bought eight 2" #6 screws, and brought them up from underneath the mobo and used the old blocks to clamp the water coolers to the board. It is now my server, running 8 3TB hard drives using FreeNAS. Backup plugin is synchronicity.

Good day to the community,

 

I am refreshing this thread, since I am one more person, facing the same problem like the guys already posting here. There is nothing less than a big truth on this statement:

I know this thread is dated, but I have seen a lot of the 775 boards and CPUs coming up for sale, and thought this might be relevant....

 

I recently bought a H100i, hoping that it would fit on a PC under construction, utilizing a (modified) Gigabyte GA-EP45T-DS3R motherboard, with an Intel Xeon X-5492 CPU fitted on it.

 

(The GA-EP45T-DS3R is one of the very few LGA-775 motherboards that accept DDR3 DIMMs. Others that I know are the Asus P5QC and the Gigabyte GA-EP35C-DS3R. There may be some more, but certainly not many).

 

The X5492 is a real power beast, with 150W TDP and it requires good cooling, especially at O/C conditions. The Corsair Liquid Coolers are excellent solutions. Therefore, my initial choice for a H100i seemed to be ideal. However - and this was a mistake of mine - I did not check its compatibility, having in mind my previous experience with the Hydro H80 Cooler, which is compatible with almost all Intel CPU sockets, including LGA-775.

 

At this moment, I am stuck. I have the following choices:

1. Try to find a backplate for socket 775, something like this and then (hopefully) try to find some screws to fit. The problem with this is that the H100i I have, came with its mounting bracket already pre-installed and it cannot be removed, to allow me drill new holes, to the spacing dimensions of socket 775. Therefore, in this case, I have to do the drilling with the bracket in place, a very risky and difficult job. Not to mention also that if the steel of the bracket is really hard, drilling becomes more difficult (although I hope that using cobalt drills will do it).

2. Replace the H80, which now is used for cooling an Intel i7-6700k, with the H100i and use the first for cooling the Xeon. However, this also will require a complete disassembling of the PC using the i7 and moving all of its hardware in a new case, to accept the H100i.

 

I am not sure if taking the risk to "modify" (drill) the H100i mounting bracket is a better solution than just do the whole disassembly-reassembly job.

 

Your suggestions?

 

P.S.:

BTW, is there any way to remove the Mounting Bracket from the pump header, so I can work with it, without taking the risk to damage the pump assembly?

As I stated above, this bracket seems to be permanently fitted in place (factory fitted) and no matter how I tried to find a way for its removal, it is impossible.

Am I missing anything?

 

Thanks in advance

Has anyone seen it?

I have just modified my old H80i V2 to fit a socket 775 motherboard.

To remove the bracket from the pump unit, it just twists off.

 

I then offered up an old LGA775 cooler to the pump bracket, and using a rotary tool like a Dremel with a milling type attachment, I enlarged the bracket holes.

 

I have mocked the install up on an old dead LGA775 board, and used the plastic nuts from the cooler bracket on the underside of the motherboard, but inverted so that there is no play. To do this, you need to remove the nuts from the slots.

 

Everything seems to fit, so now to transplant it onto the system I want to use it on.

[CageyH]

The only thing you need to change from my setup, is make sure that you fit a LGA775 backplate to avoid deforming the motherboard.
