Hello people,

I am having bad situation, my cpu was reaching 90 C, while playing Cs:go and battlefield games, So i decided to clean my cpu fan, i cleaned it with air blower and it was still reaching 88 to 90C while playing games. so i took out cpu cooler and washed and cleaned well the metal part of cpu fan , applied new thermal paste ( i applied pea sized of drop in middle of cpu and my cooler is attached well in socket ) and its still reaching 90C.

Though my cpu idle temprature is perfect ( 36 to 42 C during idle ) but if i play games its reaching to 90C. I have heared about Thermal paste's break-in time. is that could be the reason ? do i have to keep my pc on for few days to set the thermal compound in its place ? Or my Intel Stock Cooler's fan got weak ?

My Bios showed this message " New Cpu Installed " press F1 to setup. but due to my keyboard was not attached i couldnt set it up. is this have caused problem because i have not set it up ? i dont think because before it was already reaching 90C
 
Whats your system specs, case and cpu fan.

How much tension did you apply to the heatsink screws?

Which program are you using to monitor temps? Is it set to celcius not fahrenheit?

Somes pastes need a break in period but its a subtle change in degrees less not a cure start at high temps.
 
Processor - intel i5-650 3.20 Ghz

Mobo - Asus p7H55

Cooler - Intel Stock Cooler ( It has pins not screws , i have applied enough force to move those pins down
and i dont think cooler & cpu not getting contact because cooler is getting warmth, i have also
checked cooler if it is loose by trying to shake gently with hands but it doesnt move and seems fitted well. )

Programs i use : 1 ) Coretemp 2 ) Msi After Burner


The strange thing i would like to mention. im having very little Current inside of the computer cabinet, its like when i touch the inside frame of cabinet there is so little current ( even ant would only get tickle and it only feels when i touch it with my finger , if i keep my finger in touch i wont feel any current). is that causing any voltage issues on my CPU ?
 
Those stock fans aren't good. Look for a good heatsink that doesn't require a back plate. Heatsinks with back plates are best though. Any heatsink that catches your eye look at the specs for it for lga 1156 support. Most will.

As for current going through the case it could be the motherboard but most likely psu. Should investigate it further and replace. Your cpu is isolated from the case but don't want to risk psu.
 


okey will do this. But do you think stock cooler's fan got weak ? because you know my cpu never crossed 75C while playing games and im only facing high temprature since last week. Remember my stock cooler is as old as my cpu ( 2011 ), its been 7 years. Im kind of scared that what if i still face high temp after buying 40-50 $ cooler . Any problems could be there with processor itself ? i mean is it sign that processor gonna be dead ?
 
The cpu is fine it'll be the heatsink. Have the case side open and blow a pedestal fan directly at the cpu to help cool heatsink and it's fan. Should see a drop in temps. If you see an improvement then you know its not your cpu.

Can you increase the cpu fan rpm?
 


May be the problem is here.

This is my mobo and read Point no. 3 It says about CPU FAN CONNECTOR.

Either my Mobo's connector is not working perfectly or its my cooler's connector, because when i connect cooler's pin with motherboard's connector it takes 5-6 try to work the fan. i think this is causing the problem in cpu fan rpm which is causing high temp. what you think ?
 


Okey, will try this. Thanks, will update on this tommorrow 😱
 


My processor fan's rpm is varying from 1900 to 2300, i heared about Thermal paste's Break-in time that takes some hours for full conductivity so i kept my pc On for 4 hours yesterday because i just applied thermal paste 2 days ago and dint give it time to settle down. During those 4 hours no shut down , Before i kept my pc on , my processor's temp was reaching 95-100 instantly on full load but yesterday it was reaching 80-83 Degrees on full load. so you think it will take more few hours to get normal temp humm ? :??:
 
What was the fan speed setting on and what is it now? There's a turbo mode and standard which regulates rpm as needed. Ambient / room temperature also plays a part.

What paste are you using?

Break in or cure period with only hand full of pastes can take upto 200hrs of pc usage and difference in celcius will only be a few.
 


I changed Fan speed to Turbo from bios, so it now never goes down below 2000 and avg is 2200, and im using 1$ thermal paste, its just written "Heatsink Thermal Compound" on it. i have been using it for almost 3-4 years, never faced thismuch temp before.
Do you have any idea about why i was getting 95-105 Degrees before 2 days , when i applied thermal paster and today im getting significant temp drop to 80-85 Degrees.
 
It's still too high.
I'm pretty certain, that your cpu cooler is installed improperly.

BTW - can you touch cpu cooler, while cpu is operating at high temperatures?
Does it burn your fingers? Because, if it doesn't, then there is bad heat transfer between cpu and the cooler.

And keeping your cpu at 90+ C for prolonged periods will dry up thermal-paste.
 


yes i can touch fingers to heatsink and i can feel temprature, like i touched yestered when my cpu was running at 80-83 degrees on 100% load and my heatsink was hot , but not hot enough to burn my fingers.
 
As i have troubleshooted all possible causes... even restored bios to default.

Is it possible that my cooler's 4 pin connector is broken and because of that cooler aint getting enough voltage and because of this cooler aint getting enough power to spin faster ? im saying this because Every time i disconnect 4 pin from mother board , i have to connect/disconnect 3-4 times to make the fan spin itself (does this mean connector is broken) ?
 
Please tell me you are not playing with the fan connector with power applied....

If the fan is sluggish to turn, then maybe even though the fan is turning, perhaps it's bearings are shot, and it is only turning a fraction of it's required speed to properly dissipate the heat....
 


Obviously No, i never changed any settings in bios, and also i factory reset bios too 2 days ago , still same result.

is anything fishy here in screenshot ? check voltages pls
