4790k Overheating

[gurra321]

Hello

 

I have build a new pc for a month ago and have been running it without checking temps but when i check it runs 80-90 C under 50% load. I have a 4790k 4.00Ghz and a h80i push pull, i run stock thermal compund, should i try to change it ?

That's too toasty. The paste should be fine, check your mounting that it's making complete contact.

[Firearm2112]

Try replacing the compound. The H80i should have came with some pre attached. 

[gurra321]

I have tightend the screws multiple times now and i cant do it more without ruin the screws

[gurra321]

I have just using that compound their were on it but will it cover the cpu.

[CowsGoRoar]

What's the voltage? Many motherboards overvolt their CPU's at stock voltage. You can check that my using CPU-Z or any overclocking software, or go in your BIOS.

[L.E.D]

Change the thermal compound, clean rad and fans. Keep in mind the h80i isn't a massive cooler

[gurra321]

Core voltage is 0.793 V and its running 4.00GHZ. I know its not the biggest cooler but when i watch videos with same setup it runs cooler

I have a 4790K and a H80i getting 4.6GHz and max load temps around 60 degrees. I know this may sound stupid but you did remember to connect the SATA power from the pump to your PSU? Just asking since I actually made the mistake thinking power comes from the three-pin connector on the pump.

redo the paste and when reattaching the block be sure you tighten the screws evenly. if you screw 1 side in then the other the block may not be making flush contact with the cpu even if the screws are tight. this is probably the third time ive seen people have issues with a cpu temp and it was almost always that it wasnt screwed in evenly

[gurra321]

I will check all that, tomorow i live in DK so its late now i will write back if it dosent helt

[gurra321]

i have checked the pump and its plugged in but im running it with my ssd and hdd and optical drive could it be its not getting enough power ?

[Connor]

I doubt power would be an issue. Did you plug the RPM lead into your motherboard (I have a CPU_OPT 3-pin header)? What RPM are you getting? I get around 2300 RPM and would expect you to get the same. The pump should be run at max RPM all the time.

[gurra321]

Yes i plugged the pump into cpu fan header and the fans into the pump itself and im around 2300 pump and 1600 rpm on the fans and if i run fans max it dosent make a diffencen

[gurra321]

What thermal compound can you guys suggest ?

[LogicalDrm]

Core voltage is 0.793 V and its running 4.00GHZ. I know its not the biggest cooler but when i watch videos with same setup it runs cooler

 

Thats probably what it is on idle. How about under load when you having the temp troubles?

[gurra321]

underload its getting around 85-95 C

[Dennis Caplinger]

underload its getting around 85-95 C

I believe he was asking what your vcore is shooting up to during load.

[gurra321]

Ohh i will fint out

[gurra321]

Its around 1.123

[runit3]

Its around 1.123

You should not be getting those temperatures at that voltage. Do a complete remount/reapplication of thermal paste and make sure both surfaces are cleaned with 99.99% isopropyl alcohol before you reapply the TIM. Also double check the mount to make sure it is getting proper contact with the CPU. An easy way to check if you're unsure of complete contact is to cut some small rectangular pieces from a sheet of printer paper and insert them between the CPU and the block about 1.5-2mm in on each side, tighten down the screws completely, and if you can pull out the paper it's not making contact. Obviously, remove the paper before you power/boot up

[Growlith1223]

This sounds a bit dangerous but it worked for me, try lightly pressing the block(on the cpu) down onto the cpu a little bit more with your hand, if it goes a LOT cooler, it means it's not seated properly, idk that's all i can really think of

[Dennis Caplinger]

Its around 1.123

Thats not the problem then.. mine hits gets up to 1.31v and only reaches 70... I'm also delidded though.

[gurra321]

i have bought some artic silver 5 thermal compound and im gonna buy some alcohol to clean the cpu and block tomorrow and try it

[mister_s]

Just for the heck of it, if you have a different cooler try it and see what the results are.
