High CPU Temperature Causing PC to Slow Down

[Khan]

Hi,

I noticed my computer running slow for past few days, i was getting low fps, i thought it was my GPU. But i checked the temp today using http://openhardwaremonitor.org/ and in my bios my CPU is showing as 97-99 `C consistently.

Ive noticed my closed water cooling system has been making a lot of noise recently as if im doing something which is very CPU intensive. I checked my CPU usage in task manager and its usual idling speeds 5/6 %

This high CPU temp is most likely the cause of my slow computer?, How can resolve this issue? is it caused by my fan?

This is my fan - https://www.aria.co.uk/Products/Comp...roductId=62826

Give everything a good clean out. Get rid of all the dust in the fans and radiators etc etc.

If you're confident doing it, replace the thermal paste on your CPU.

i would guess your pump is dead/dying and not moving the fluid around the loop efficiently.

i would look at something like this if you just want to fix it or something more like this if you want some top tier air cooling. that or replace it with another water cooling loop?

I watched this video, https://www.youtube.com/watch?v=CL_HkQF0dZE it seems i just need to unscrew the block, apply paste directly on the CPU and screw it back in. Is that right?

Possibly, ive had it for 3-4 years now.

Will those fan fit my case and how does it compare with the water cooling?

Also if i switch to air, i need to buy extra fans in place where the top water cooling radiator was?

I also noticed in my msi command center it says CPU fan 1 and CPU fan 2.

But CPU fan 1, does not seem to be doing anything..

Remove the block, wipe it clean (use isopropenyl for better results but something like a wet wipe works fine), apply some new thermal paste, secure the block in position again and ensure the radiators aren't clogged with dust. If temps don't improve, it might be time to replace it.

In regards to your CPU fan 1 issue, your motherboard might only have 1 header for CPU fans (PWM fans that spin faster as temperatures increase) and its a red herring from the software or you have your cooler pump connected to the one of the headers, if your motherboard has 2 CPU headers.

My motherboard is a MSI 97A MS 7916, i can see that there are 2 ports plugging into something labelled CPUFAN1 and CPUFAN2 on my motherboard. I assume this is correct, aria built my computer, so im confused why the command center is not showing any RPM for CPUFAN1. Is this an issue which could be causing high temps?

In the below image you can see in the top right CPUFAN1 and CPUFAN2 both are connected by what appears to be my cooler wires.

One will be the pump which is why its not showing a fan spinning as its not a fan connected

im having trouble re screwing it back in, the screws move around ebcause the metal bit has 2 holes. if that makes sense. any help?

[Khan]

Wht i mean is should all the screws be position on the outside or inside hole

Theres a backplate that the holes line up with, all you should need to do is gently push one of the screws into place and turn the screw a few times so its secure (not tight) before moving on to the one in the opposite corner. once they are all in place, tighten them up fully and you're good to go.

Sounds like the pump isn't working. Can you feel it vibrating if you put your finger on the block?

[BigIan88]

Line all 4 screws in to position without tightening them, that'll tell you if its the inside or outside hole on the moun that should be used. It should have instructions that will tell you which hole fits which socket.

Backplate, there should be something else under this block, or do you mean the screws mounted onto the motherboard?
