High cpu temp on stock cooling 4790k

[tolagarf]

I actually ran a stock cooler on my i7 5930K for a little while. It didn't hit more than 65 degrees Celsius (with Prime95 even!). So consider that your cooler is either faulty or hasn't been installed correctly. Also get some pure alcohol and clear off the black goo on the cooler, then use some real thermal paste. Not sure if this could be the issue, but I do know if you don't use thermal paste with those stock coolers, the CPU will get hot.

Cooler Master Hyper T4 should help you out and its relatively inexpensive if you dont mind air-cooling. I have a similar Hyper N520 but I have a different socket, these two are pretty similar and I have never had any issues with mine at all.

To keep my CPU from exceeding 60C in games I've down clocked my 4790K to 3.1 GHz @ 0.8v until I get around to watercooling it next week.

Get yourself an aftermarket cooler, even a cheaper one like the freezer pro 7 would make a huge difference as long as you don't plan on overclocking.

It may be bad, but still, at stock it should not hit 90C so I still think he has a problem. Unless his case air flow is also poor.

Then go into the BIOS, change your CPU voltage to manual and start undervolting your CPU. "Auto" voltage in BIOS is going to be too high. Start with around 1.1v, then run stability tests like Prime95. Keep on lowering the voltage incrementally until it fails the benchmarks, then set it back to the lowest known stable voltage.

Both of these things will drop your temperatures down significantly.

Have both of you done this? If not, do this. If you still have temperature issued after this, come back and we can look into it further.

Yea I'm sure I put it on right in the first place but as I said I'm going to rebuild my rig next week and that will solve this issue for me.

I'm going to put it back under water and I had no issues previously with a setup like that. I might even delid and run direct to die and see if I can knock a few degrees off. I don't think Intel's NGPTIM process worked well on my CPU anyway.

Doesn't help the Op much though...
