CPU temperature 100C under load

George Roberts · 11 Aug 2020 at 17:10

I've just fitted in the new cooler and the CPU now reaches 85-90C under load.

Is there any more I can do to get the temp down?

Did you turn the rear fan around so it's blowing air out of the case?

Also bear in mind is very hot today so you would expect to see temps around 10c lower on a normal day.

1 intake and 1 exhaust fan is not enough imo, would be adding at least one more intake preferably 2.

Take the side panel off your case and then test. What are the temps ?

I did turn the back fan around yes.

The temps are 90-95C now. Even on a hot day like today, is it normal for your CPU to get this hot?

What do the idle temps look like and did you test with the side panel off the case off as Micky suggested as this will give you an idea if it's the case airflow that's causing the higher temps.

Idle temp is 45C. When I take the side panel off the CPU temp fluctuates between 85C and 95C under load, mostly 90C+

Is that with the cooler fan at 100%?

George Roberts · 11 Aug 2020 at 19:57

How do I check/change that? I'm just going by the numbers that MSI Afterburner is giving me

George Roberts · 11 Aug 2020 at 20:03

I have no idea if my fan is at 100%, I presumed it was but didn't know

Joxeon · 11 Aug 2020 at 20:05

There should be an option in the bios for adjusting the fans.

Which motherboard do you have?

George Roberts · 11 Aug 2020 at 20:19

I have this motherboard MSI Z270 PC MATE ATX LGA1151 Motherboard
I turned the fans to full speed but it didn't help

What kind of voltage and speeds is it running at?

George Roberts · 11 Aug 2020 at 20:52

CPU1 2050RPM
SYSTEM1 1400RPM
SYSTEM4 1400RPM

System fans running at 12V, no idea about the CPU fans

I mean the cpu speed in GHz and the CPU voltage. Possible system is already applying an auto overclock causing high temps likely due to high stock CPU voltage.

Download CPU-Z and where it says core VID there will be a voltage to the right of this. Ensure system is under load. And again core speed near the bottom and again report what that is under load.

Does this CPU have craptacular TIM under the heatspreader?

Possibly needs a delid and some liquid metal?

George Roberts · 11 Aug 2020 at 22:26

I've downloaded CPU-Z and it doesn't say core VID anywhere but does it say Core Voltage 1.160V

I'm a complete noob when it comes to these things, so I have no idea what you're saying

George Roberts · 11 Aug 2020 at 22:39

CPU speed is 3.6GHz
