can some one tell me if i used to much thermal paste ?

post #1 of 6
Thread Starter 
I re mounted my corsair h100i and I used cooler master htk-002 high performance thermal paste at first I put a grain of rice size drop of thermal paste I tried to get it in the middle of the cpu but it did not go directly in the middle so I put another grain of rice size drop towards one of the corners of the cpu did I do the rite thing to add another grain of rice size drop of thermal paste ? or did I use to much ?

Possibly. You are not really giving too much information. are you now having heat issues? What kind of thermal paste are you using? If it is conductive like Arctic silver you need to be careful none seeps out and makes contact with ANY metal parts or you can have a short.

Ideally what you want, pretty much regardless of the type of thermal paste, is the grain of rice or pea size. Place your cooler on top carefully and start to tighten. before it gets snug you want to wiggle it slightly as you tighten down. This will spread the paste to cover the cores that need the cooling and evenly distribute it.

a pea and a grain of rice are way different in size.

I have always found the grain of rice to not be quite enough and shoot for HALF of a pea, to me I would say this is 2x as much as a grain of rice, but maybe I just eat small rice?

I also like to heat up my paste wrapped in a hot towel. it just seems to spread easier when you set the heatsink on it.

It also matters what CPU are we talking about. The size of the CPU's heatspreader matters. For example, a Sandy Bridge E IHS has more than twice the surface area of a Sandy Bridge IHS, thus needs roughly twice the amount of TIM.

Warming the paste up definitely helps. Especially with pastes that are really thick at room temperature. I've tried the pea sized dab in the center and agree that it sometimes doesn't spread well. Personally, I like to put a thin line about half the width of the IHS horizontally through the center of the CPU

I put the dot on CPU's sometimes a line depending on dualcore / quadcores / amd cores trying to "follow" the direction of the actual die under the IHS, and I put a big "X" on GPU IHS for nvidia.

when doing direct to die, I spread it so the paste pads the heatsink from cracking the edges or corners.

It still doesnt matter, as long as the paste is between where the heat comes from, and where you want it to go to.
