high cpu temperature when running Intel Burn Test

[JoJoMix]

Hello everyone,

I had a lot of help from this community in building my new gaming pc and I really don't have much knowlege on picking parts or assembling the pc. So after few days of searching I assembled this pc:

cpu: i5 4690k
mobo: gigabyte GA-Z97-D3H
ram: Kingston HyperX Fury 8GB 1600 x1
gpu: gigabyte gtx 780 windforce x3 oc
HDD: 120 GB SSD kingston + 1TB seagate baracuda 7200rpm
psu: corsair CX 750M
case: cooler master 690 cm III
cpu cooler: cooler master seidon 120m (came free with case)

The cpu cooler was bundled with the case and was really close in price if I get a CM HAF 912 case + EVO 212 plus cpu fan. I dont have knowledge in building pc and wanted it urgently so the shop did offer to assemble it for free.

PC is working well and nothing wrong with it so far but I did notice slightly high fan noise when playing games so wanted to know if the liquid cooling is attached well. I ran prime95 along with RealTemp and from pictures you would notice it hit 75 C max. Then I tested Intel burn and temperature hit 100 C and you could see LOG thermal status in RealTemp. Both tests did like 100% cpu load so why is intel burn test made cpu reach 100C?

I thought maybe liquid cooling seidon 120m is weak or not installed properly and so did take photos for the case and the way fans are installed. One suggestion I found online is that seidon fan could be mounted on the back of the case and pulls fresh air from outside into the case. In my case it does pulls air from outside but it is mounted at the top?

Also I did find an extra strong fan laying around and did mount it at the bottom of case so it pulls cold air from bottom then into the case.

Last I began to hear ticking or noisy sound from the pump which is shown in the video.

More info: I download all the software from Gigabyte for the motherboard and did set the auto OC which was chosen to be 4.3GHZ.

I would recommend turning the fan/s around so that it's pushing air out of the case and not into it. Keep in mind though that both those programs will inevitably raise your temps as they load all the cores up with work and are really meant only to see system stability and not day to day performance.

hey CDdude55

If I understood you I need to make the fan on top of the radiator so it pulls air from case through radiator and then out right? That seems good but I found other people configuration switching the fan at the back of case to top and the liquid cooling at back taking air from outside (fresh cold) into the case. So warm air from radiator comes in and the top fan will take it out. Does that seem good?

Also regarding the test I read that if I use a good case with fan and liquid cooling then the test should be fine as I have a hp dv6 laptop and temperature was around 70 to 80 running prime95 where in this pc temperature seems unusual and should be a bit cooler right?

I was thinking maybe setup is wrong, or thermal paste was wrongly applied as the stock one was used or pump is not working properly ( it uses 3 pins not sure if needs to be adjusted from the bios)

Thank you very much

Hello,

I just tried to inspect the problem myself. Noticed that the pump is connected to CPU_FAN and the radiator fan connected to CPU_OPT where I found online that it should be connected other way around so did change it and modified bios to make cpu_opt run at full speed.

Second I wanted to inspect the thermal paste so tried to remove the four screws securing the heatsink with pump but found that the screws were damaged and I was unable to unscrew the threads (seems stuck and the whole thread keep rotating). Shop did the damage so contacted them and would bring the pc to them on Saturday to fix it and for now did try to tighted the screw in a way that it holds securely.

Now I am amazed with the results although the pump is not really secured as it should be because of the over-tightened damaged screws. Look at the new results for prime95 and intel burn test. I got -20C resutls compared to previous one.

Yeah as I tell many people, you have to be sure the pump gets a constant 12v feed.

Hello Rob,

Even before changing the pump socket from cpu_fan to cpu_opt, I made all the fans in system running on max setting before the first test and still got high temperature results. I don't think the change on socket made difference as I did feel the coolant being pumped when touching the pipes.

I guess the problem is from the damaged screw and the heatsink was inappropriately mounted.

Last, would you suggest me any good modification for this case and where to add/modify fan to get the best air circulation? Thank you very much

Just some decent airflow fans will be fine. Your case can take 200mm fans in front and top, so one for each of them might be a good idea.
