Thermal paste. What the heck?! - Page 2

AS5 was released in an era before most CPUs had integrated heat spreaders, so we were instructed to spread the compound over a bare die. This is necessary when the whole surface is the IC, but is not the best way for lidded parts.

Center of the IHS (the metal lid on the CPU).

I see. Well, I have an i7 CPU if that helps. I know not to get it on the PCB part of the CPU.

The i7 920 has a very large IHS. Just put a dab of TIM in the center or a line down the middle.

Okay, using acronyms I don't know. IHS? TIM? I'm sure I know what TIM means, just never heard them used before.
post #15 of 18
IHS = Integrated Heat Spreader. It's the metal (nickel-plated copper) lid over the CPU's silicon die...the silvery cap on your chip that is about 80% of it's mass. It primarily protects the CPU, but also allows high heat density parts to be used with cheap aluminum based heatsinks.

TIM = Thermal Interface Material. This is anything intended to conduct heat from one surface to another.

Warm the tube under hot water for a couple minutes to soften up the paste. Problem solved. It's great paste, just needs a little bit of work to get it to spread easily. However, as others have said, just use a decent sized dot in the middle and let the heatsink spread it out. Then just check your temps to make sure they're good. Formula 7 has no curing time in my experience, so if the temps suck, you did something wrong.
