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 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.
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
