Worrying prime 95 temps.

[Soumyadeep28]

I have an i3 6100 and I ran prime 95 test on it, the small FFT one. My CPU temp is rising up to 80-degree celsius within 10-15 seconds. I have read other threads where people say their i3 6100 runs at 67 degrees on 100% load with prime 95. By the way, I am using stock cooler and the 67 degree one is too. I would like to hear what other people with an i3 6100 get temps using prime 95.Is there anything to worry? is my Cpu bad? Do I have to take it to a service centre?

Hi my friend.
Prime 95 is such an extreme stress test so I don't recommend it.
It could easily destroy everything.

Actually I have a problem with this. Why on earth is people thinking they need to run a stress test at all?
This must be a myth,

If You must?
Instead, use Intel Linpack and while this is also a power tool , it will not damage Your computer.
Especially when stress-test the memories

Use LinX a derivat from Intel stress test, it will also work on AMD

Without using stress test, how can I check how much is the cpu heating on 100 percent load ?

or in my case CoreTemp

But I didn't understand why I got 80 and others only 67?

Hi,

It could be that the two different temps. are causing due to the fact:
Package temp sensor (the real important one) which is seated just beneath the top cooling plate of the professor.

Then there are others inside the cpu chip itself, however these are not real core temp sensors, instead they are virtual ones, calculated values from each core load and the package temp. sensor.
Now, even so the the temp sensors from its individual cores are actually quite accurate and usually correspond very well to the real temp. sensor at the top-plate of the professor.

Why You have this big discrepancy I can't understand, but download the free HWmonitor and check all the temps.

Make sure to clear the check-box for any third party s/w during installation.

There are three columns: Value which means the actual readings right now.
Min and max speaks for them self's.
Best regards from Sweden

[Edit] Have HWmonitor on, then start a heavy task such a game or something, after a couple of minutes check the readings from all temp sensors, especially the Max column and compare.

What version of P95? The temperature will be significantly lower with version 26.6; newer versions make it run really hot. If it doesn't reach 100°C using the current version of P95, then you don't have a cooling issue since nothing else will ever make it run that hot. Running it for more than a few minutes would be useless.

The version is the latest 28.10

Then it's normal. Try 26.6 and you'll see much lower temperatures. ftp://mersenne.org/gimps/p64v266.zip
