CPU overheating under load on 90c+

[Rikos]

Hi,

Lately I have noticed some var spikes during playing cs:go, which caused frequent frame drops. A friend pointed out to me to use speccy and try to find my CPU temperature. The result was that I have around 30c idle and 90c under load (cs:go for example). Keep in mind I am using an H100i water cooler which I bought in the summer of 2015 and have never changed the paste. First I tried to see if the fans where not working at a high rpm under load. I realised that speccy, corsair link and the BIOS where showing around 1100 rpm, when I can clearly hear the fans changing speed. I have used both the stock fans that came with the cooler and 2 Noctua NF-F12 with not much of a difference in temperature nor in rpm. So I thought it 's probably the BIOS fault and tried to find my version. Apparently, I have the 1.8 version which is not even available to download on the msi site. What should i do?

My Full PC specs:

CPU: i7-4790k, not overclocked

GPU: Asus GeForce GTX970 4GB Strix OC

RAM: 2x8 Corsair 1866MHz

MOTHERBOARD: MSI - Z97-GAMING 5 ATX LGA1150

PSU: Corsair CX600M

CASE: Corsair Carbide 500R

 

HARD DRIVES: 250GB SSD Samsung 850 EVO, and a 1Tb Hard Drive

does the pump still work? listen to it or feel if the tubes are vibrating a very small bit

1) Is your system even free of dust on everything, including radiators?

2) What about pump? Does its RPM increase?

3) If other 2 things are checked and fine, I would suggest changing thermal paste and play with undervolting (since haswells and Devil Canyons are not easy to cool).

The pumb doesnt seem to be working. The tubes arent vibrating nor does it make any sound. Thanks for your suggestion

1) I cleaned it a few days ago

2) I dont know, but the fans on the readiator dont

 

It looks like the water cooler might have died, but that still doesnt explain why the rpm on the programmes stays the same when i can clearly see and hear that it changes

Did you use "Corsair Link" on pump to check pump RPM? Fans are a different story, though... Try to check your pump.

It's at 2256 RPM

Yep, there's your problem. The fan speed will change regardless of whether the pump is working btw.

Yea, but corsair link shows RPM on the pump. Could it just be that it's out of liquid?

It's most likely a glitch, because the pump is dead. (Right?)

hey man ,if it sit at 30 c idle and then as soon as you do something goes immediately up to 90 that means that the heat within the chip rises and there is nothing to keep it from continuing to rise and cool it down fast enough , so something in your cooling chain isn't working well enough , also some more info on the kind of stress you put it under would be an indication whether or not you need to go through the steps i will mention now 

1.change thermal paste ,3 years is a fair amount of time to do so 

the first step is about the thermal problem the next two are about the issues you have with the numbers shown 

if you still have thermal issues after re- applying Thermal paste ,change the cooler ,see if you have the stock cooler lying around or something you might be able to use to see if there is a difference 

2.download the latest bios for your motherboard ,you do not need a special version,(the version you already have 1.8 ) ,you just need the last version released by MSI for your motherboard , its here http://download.msi.com/bos_exe/mb/7917v1D.zip  version 1.D released in 2016 this should make a difference with compatibility issues with corsair link and your bios ,or not, but its good to have the latest 

3 Clean install windows , it don't get this one either but it makes a difference sometimes 

again before all this see if the kind of load you put it under IS the issue first

I have checked again and I must have been mistaken before. The pump has a slight tremble to it but it's still hard for me to recognise the pump's sound.

trying a different cooler will help you stop guessing what is wrong , looking through software and bios numbers , if its the pump or whatever else , in your case it doesn't make a difference,  its an AIO cooler you cant replace the pump alone anyway , you will have to replace the whole thing 

BUT first re apply thermal paste just to be a 100% sure

I used prime95 and runned a test stress. The cpu went up to 95c. I don't have a spare cooler, i'll try to find one from a friend or just get a new one instead. Also I am not really sure how to update the bios.

[Rikos]

Thank you all for your replies

[NBPC]

DUDE prime 95 ! is very stressful for ANY Cpu so there is that , i was testing an 8700k a couple of months ago and i couldn't keep the thermals under control on that with a brand new Celsius S24 so no surprise there , to install new bios you take the ROM file unrar it if its in a rar place it in a usb stick i think it has to be formatted it fat 32 not entirely sure about that then boot into bios there will a message in start up telling you the key you need to press to boot into bios its usually the del or F1 and there should be an option in there
