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"...
