H100i on Hackintosh


Recommended Posts

Hi everyone.


I know these questions have probably been asked a thousand times but I think my issue is ever so slightly different.


Basically, I've built a Hackintosh Pro which has all the bells and whistles and decided to go with the H100i even though I don't dual boot so I can't get the USB services to work.


Anyway, I thought I'd installed everything correctly except that the Radiator and fans wouldn't fit in the case so I had to put the radiator above the motherboard and then the fans above that on the outside of the case.


Booting into the UEFI bios I can see that the pump is working at 2368 RPM with the CPU running at 46degrees which I thought was a bit warm.


Booting into OS X and my idle temp is now down to about 30 but under heavy load, for example, rendering a file in Cinema 4D the CPU is at 100% and the temp hits 100 Degrees. As soon as the render ends, the temp is back down to 30 or so.


I can only assume that it's working but then, if that were true I wouldn't expect the load temp to be so high.


Interestingly, when starting up the computer the fans go all out, but even under heavy load, they never seem to spin that fast. Could that be the problem?


Aside from the obvious suggestion of installing windows (which would mean buying it). Has anyone got any other theories/solutions?


The build is


Corsair 500R Case

32Gb Kingston Hyper Beast Ram at 2200

Samsung EVO SSD * 2

WD Green Drives * 2

Gigabyte GTX 770 4GB

Gigabyte Z87X-UD5-H

Intel i4770K


Also, find attached a link to a pic of the temps under high load

Backplate is definitely correct.


Think I'll do the thermal paste this week.


Also, forgot to mention that I had used the UEFI to boost the performance in one of the settings to 20%.


As a test I knocked it back to auto (normal) and just ran the same test in Cinema4D and under full load it's maxed out at 70 Degrees, so I assume that was the problem.


Probably should have checked that first!

The stock paste is already very high quality stuff, but if you still want to investigate the issue, changing pastes shouldn't negatively affect the results. Just be sure to use one of the higher quality pastes (like MX4 or Shin Etsu 7783). Also, check the clearance of the capaciters near the processor (the tube-like metal canister-shaped things). On some motherboard models, they may interfere with the pump housing, causing it to not sit flat on top of the processor.


A third thing to check is the thickness of the motherboard itself. Some motherboard manufacturers have begun using non-standard-thickness motherboard PCBs, resulting in a thinner board, and thus a loose pump housing. If this is the case, some nylon or rubber washers can be used as spacers to ensure a proper fit. There are posts around the boards here with more details regarding this solution should it be needed (including the exact size/thickness of washer to use, etc).
