I just recently built a computer and i wanted to make sure my rig was stable. I got real temp and prime95 and started testing. At idle with the i7 4790k and the corsair h100i i was averaging 32c. Thats kind of high for idle but it didnt worry me. Then i started prime95 small fft and wow did the temps rise. They went to 100c. I know small fft is max stress for haswell chips but it scared me. Then i tried large fft and the temps were at 88c average. Im using the corsair h100i in a pull exhast because i couldnt do push exhast due to my heatsink on my motherboard in the NZXT Phantom 530. This will prevent dust in my radiator at least. Corsair link is totally not working for me to control the fans. Im running the corsair sp120 quiet edition fans powered by the corsair h100i. My motherboard is the asrock z97 extreme4. I heard that its doesnt work well with my motherboard. Also, the corsair sp120 quiet fans arent pushing much air out of the case which worries me. Worse case i will just buy some new thermal paste and reinstall it. Im using the stock thermal paste for now. And I might try replace the sp120 quiet fans with the stock fans to see if that improves anything. Sorry for this being so long and please help.

Check whether the backplate is properly fitted. Reseat the CPU block and reapply thermal paste.

^^^^^^ Follow that and if it doesn't work, then there might be some issue with the pump, i suggest get a new water cooler or RMA it.

Replace the thermal paste with some MX4.

Also remount your CPU block with small washers behind the motherboard, sometimes the backplate is loose even though the screws are all the way in.

The pump is working. I checked the bios to see if it was dead but its working. Also, i can feel it vibrating in the tubes.

Obviously i took off the cover and it comes with decent quality thermal paste.

The 32C at idle is identical to my idle temps with the i5-4670k, so I don't think you need to worry about the idle temps.

 

As for the other temps your best bet may just be re-mounting it and make sure you use the washers.

Use washers where?

Backplate or Radiator?

The backplate, since that's where it will affect the cooler contact with the CPU. A common cause of those high temps can be poor CPU to Heatsink contact, and the H100i needs those backplate washers to make good contact.
