another i5 750 too hot thread

[c0d3ster]

Hey everyone,
I have been having problems with heat and my i5 750.
It is clocked with stock speeds and the stock heat-sink and fan.
I bought some thermal grease, but I'm not sure it is the right stuff..
I attached a picture below.

my current situation is that I idle at about 45-50 and at about 50-53 after the computer has been running for a while.

When I played battlefield bad company 2 for about 30 minutes last night, i noticed my temp got up to 90c!!
This seems harmful to the computer..

I took off the heat-sink, cleaned the old thermal paste, applied the stuff shown in the picture above, and re-set the cooler.
I also cleaned all the vents and took off some covering to keep dust from getting in.

My fan speeds seem like they are set correctly..

On the package it says "4-PK 2 Gram Injection Tubes Thermal Grease For CPU
Fans"
It just seems like I may have applied wrong "thermal grease"...

i found the stuff on amazon

it comes with a spatula like you are supposed to use it as CPU thermal grease, so i am confused
also says "T-grease 800 series" if that helps anyone identify it..

Thermal Conductivity: 3.8W/m-k
Thermal Resistance: 0.017C-in W

That Evercool thermal compound is probably junk. You should buy some Arctic Cooling MX-2. it is cheap and very easy to apply for beginners.
The Evercool crap isnt going to damage anything, but surely wont provide the best thermal transfer.

Also, you should consider getting a better aftermarket cooler. The stock one isnt bad, but 120mm heatsink will cool better with less noise.
This Corsair A50 is only $22 after rebates (free shipping too) and should do a good enough job of cooling that processor.

Or for a few bucks more you can get a Cooler Master Hyper 212 which will be perfect for the 750:

Thank you very much!
I ordered CM Hyper 212 plus just yesterday.
My main concern is that it won't get here till the 13th-16th.
I want to be able to play games until then without worrying about my i5 getting too hot (90c!)

Think my best bet would just be to clean off the old paste and re-apply new?
Would rotating the stock cooler 90-180 degrees make things run cooler maybe?

thanks for the help!

Gaming @ 90C is not ideal but it wont break you CPU. Those temps do seem very hot for a default speed. With me messing around with the intel CPU, i notice on mine the tabs where made out of plastic and sometimes it was not flush to the board making good contact on the CPU. I think that might be happening in your case. Keep gaming and replace that CPU once it comes in.

Its not going to hurt to re-apply TIM (wont take you more than 10-15min IMO)
It also looks like you have plenty of that evercool stuff

Try different approaches, Line method, pea method, etc and see what gives you the best TIM contact (mount the heat sink, then remove to check for coverage). Rotation with the stock cooler should not matter.
