i5 2500k Tempature Questions

post #1 of 21
Thread Starter 
I just built this computer a week or two ago.

I just tried gaming on it finnaly and i noticed my tempatures on Core Temp are scaring me.

Right now just typing in Web Browser


38C
37C
39C
39C

I did prime stress test and when it hit 86C 30 seconds into it I stopped it.



When I play BFBC2 My temps started at 65C went to 77C then nearly to 85C then went down to 64C.

So now I'm afraid to even use the machine.

I used a rice/pea size of thermal paste that came with my ThermalTake Frio cooler.

Sometimes when I play BFBC2 my 4th core is maxed out and the other cores are sitting at 35%.

I don't understand what to do. My room is rough 75-80F

I have the push and pull set up going with the Frio fans and I have them turned up to nearly 60-70% fan speed constantly.

I'm running at stock no overclock other than turbo boost running sometimes pushing to 3.7 Ghz

There might not be enough paste then. I used the stock paste too and I did this:
  1. Applied the paste to the CPU
  2. Installed the heatsink all the way
  3. Removed the heatsink
  4. Inspected the thermal paste application
  5. Added a little more because I needed to
  6. Installed the heatsink all the way
  7. Removed it
  8. Inspected the thermal paste application
  9. Applied about 3 tiny little specs to 3 different areas that seemed like I missed
  10. Removed the heatsink
  11. Inspected it
  12. It was good (full coverage). Whew.

It wasn't as much work as I made it sound, but it was worth it! My maximum temps with several hours of Prime95 Blend @ 4.7GHz with 1.384V ended up being about 70°C. Although, my ambient is always about 70°F.

Plus, I also have these fans on the Frio:

I keep them at full speed during a stress test which is approximately 2500 RPM (with supposedly 110 CFM), and right now I have them at about 1400 RPM which is resulting in a 29-31°C idle range.

However, I think that it's my paste application, not my fans. My fans are great, but damn: they're not miracle workers.

So one pea size dot and then mounting Frio was not the best thing to do?

What do I use to clean the thermal paste off?

Meh, I think that you don't have to worry about that. I say just check it and if you don't have full coverage that is relatively even, then apply more where it's needed. Although, if it is crusty, then you can use Isopropyl Alcohol and a paper towel and even a razer blade to "shave" off the crusty paste (use a low angle like a shaver). It doesn't have to come absolutely perfectly clean and spotless, but at least make sure it's smooth to the touch.

If it's still gooey, then don't remove it. Instead, just add if necessary.

Also, I suppose it doesn't hurt to try and evenly tension the backplate on. I mean, use a criss-cross pattern: tighten one screw down a little, cross over and tighten the other, pick one of the 2 remaining and tighten that one down a little, cross over and tighten that one down a little, and repeat until all of them get completely tightened at the same time - in a sense.

I'm a drummer, so I kinda applied the same approach that I use when I install a new drumhead: at first, I do what I can to tighten the head down evenly using a criss-cross pattern, gradually tightening each tension rod down one after another.

The purpose is to hopefully not squeeze the paste in one direction, kinda like putting ketchup and mustard on a hamburger and then putting the bun down and pressing one side instead of trying to apply even pressure all around.

However, I don't know if this makes a difference yet.

So my temps for the record are too hot.
All signs put to the paste application?

The temps you reported are safe, but they are unexpectedly quite high.

Anyway, I don't know yet if it's the thermal paste application. We are trying to find out.

Should I take my computer apart and reapply paste?

I have the paste right here but I don't wanna do all the work if it won't make a difference.

Prime95 will cause my computer to shut down if I run it for more than 2 minutes.

Even if it doesn't make a difference, you will be glad you did it because then you will know.

Knowledge is extremely powerful. I know it's a lot of work, but would you rather know or not know?

what else could it even be?
Would a new BIOS for my motherboard fix it?
