A few weeks ago the desktop that I built about 3.5 years ago was having a lot of strange issues.  First of all, I was getting cpu fan failure error. Secondly, the pc was crashing due to blue screens. I replaced the fan to solve the first issue and after some google research I replaced the ram which solve the second.  The problems didn't stop there though. Something was causing my pc to use near 100% disk and cpu usage. I had to disable some background programs such as windowsearch and superfetch. That solved that but I never had that issue before with my pc.

 

However, I'm concerned with the high cpu fan rpm.  I was getting 48C temps and 1300 rpm cpu fan.  The second time I reinstalled the cpu cooler, which is a cooler master hyper 212 plus, I probably applied too much thermal paste so I reinstalled it for the third time. This time I was very careful with how much thermal paste I applied.  Temps improved to 45C but the fan is still at 1300rpm.  I'm watching the bios screen and the temps slowly go up from 30C to 45C in about 10 minutes. As I was installing the heatsink it did slide back and forth a little bit but only by a couple millimeters. And I did correct it.

 

What could be causing all these problems? Could it be a software or hardware problem? Have I somehow installed the cooler incorrectly? Is it just a coincidence they all occurred at the same time?  My antivirus program came up with nothing and malwarebytes found only a couple of pups.  I admit in all honesty I didn't do the best job building this pc but it did work for the past 3.5 years.

45C is not particularly warm, being a warm summer day in Saudi Arabia....

 

You can't really expect it to run at 22C.

 

Apply a very thin film of paste only, less is better, and use a quality paste, like Arctic Silver, etc...

Well I was hoping for 40C idle. The cpu fan rpm is what concerns me more.. For the thermal paste, I used masscool G751 thermal compound. It is one of the cheaper ones but has good reviews. Next time I will try artic silver or something equivalent.

I have a FX8320 and, as noted above, 45 Celsius is not something to be concerned about.  I use the stock cooler with Arctic Silver.

 

The FX 8320 and 8350 are known to run slightly warmer.

My system has seen temps in the 70s when rendering video, with no harm done, no alarms going off.  Based on my experience, I believe that some of the expectations/concerns that others express re temps...fall into the category of "beauty is in the eye of the beholder."

 

Looking at your initial post...it seems to me that you have some issues which are not typical.

I am running an older AMD Phenom 2 X4 940, mildly overclocked (runs 3.0MGhz, O/clocked to 3.5MHz) and my CPU heatsink fan normally runs 1700+ RPMs. My normal idle temperature is 47°C  and when under heavy load running video editing or graphics apps such as Gimp & Photoshop, can go as high as 70. And that is with liquid cooling, not air, which dropped my temp several degrees when installed. AMD processors always run warmer than Intel processors, it's just the nature of the beast. Great procs, though, I only build with AMD. I don't see anything to be concerned about.

Modern Intel processors run much warmer than AMD ones, because toothpaste under HS. Tomorrow difference is even bigger :devil:

I guess that's possible, it's been a while since I built a new unit.  I know it is true for the older procs.
