I really think richms hit it on the nail here....

If you don't know what thermal paste is then you really shouldn't be building a pc

EVERY SINGLE motherboard manual I have ever read tells you to check the thermal interface material and even more the instructions that came with the cpu would have even shown you....

You need to be careful, sometimes the cooler comes with thermal compound already applied.

I agree with richms, I think you're out of your depth and I think you need assistance (in person). There is a very good chance you are going to fry something if you continue.

Which is useless once the machine has been powered up and its heated it and then the heatsink is removed, the pad needs to be cleaned off and a new one or paste applied.

I would suggest you get some help too.

You should carefully (and thoroughly) clean the heat sink and CPU, with a solvent like Isopropyl alcohol, before applying any paste.

Also, you need to be careful not to touch the areas you want to paste too. Dead skin cells will affect the result.

Finally, the amount of paste is critical.

You can make an even bigger mess by putting too much thermal compound on.

Too much and it can leak into the CPU socket and fry your motherboard.

Most thermal pastes are electrically conductive.

You don't need much - around a grain or two of rice. Heat spreads it out.

At least AMD CPUs are simple  - you just put a spot in the middle of the CPU.

For Intel CPUs, a stripe of paste is often recommended. It can be vertical or horizontal depending on the CPU too.

Your motherboard comes with a manual. You've not read it.

yeah found various info ranging from 45-55 to 55-62 so sits within this range.

My concern is this was from bios, what will happen when i load windows and other applications?

but are those numbers idle numbers or under load?

I have the same motherboard and almost the same CPU (AMD Phenom II x4 955).

I took a look at my BIOS/UEFI temperature was quite surprised to see it running at 56-57C.

So, decided to test the setup running Windows (Server 2012R2).

Software used... SpeedTest, Core Temp - for testing temperature: Primes95 (64bit version) - for stress test.

I ran with CPU Q-fan control disabled initially. Later I ran with it enabled and set to standard. There was no difference in results.

Results:

  OS with no applications running (Server is always doing something) - SpeedTest and Core Temp both reported around 37-38C (which is fine).

  With Primes95 running (100% CPU on all 4 cores) - Temp around 63-64C (which is also fine).

We have a major disagreement between the BIOS temperature and those shown in SpeedTest and Core Temp.

I am pretty sure I made a good job of installing the thermal paste and the CPU fan is definitely working.

I also ran SpeedTest and Core Temp on my desktop PC (Core i7 5820K 6 cores/12 threads) and got similar temperature results (cooler idle but low 60's stress) to my AMD 955.

So, I am inclined to believe that the BIOS temperature reporting is incorrect.

I have a very old (probably original) version of the BIOS - 0503. That could very easily be the problem. I may update that sometime.

One other thing you could try, if you are running Windows Desktop (doesn't seem to work on Server), is installing the AMD Overdrive application.

Apparently, it has better CPU temperature tracking.

Bios will be correct, the bios doesnt have anything in it to make the CPU idle when its not needed, so its just spinning in a loop at quite high utilization while its showing you stuff on the screen.

Check that the motherboard isnt being helpful and applying a slight overvolt and overclock to the CPU as a default setting, it should list the vcore in with the temperatures, and check that is right for the CPU. If thats up a little then it will run hotter.

Hi

I'm building a new computer (first time) and have put it together and everything seems to be working ok. However, when installing Windows 10 from a USB stick the Seagate HDD and the Crucial SSD can't be found by Windows. Also the Bios shows that the two inputs (0 and 1) are empty. The motherboard is the Gigabyte B150M-D3H.

I don't know how to solve this problem.
