Thermal Paste or Thermal Waste

post #1 of 21
Thread Starter 
So I have noctua NT-h1

Should i apply a thin layer on my i7 with a plastic card and mount my XSPC water block?


I did a grain of rice which should be covering the whole cpu but i am a paranoid mofo

i dont want my chip looking like this


i also know i am not supposed to spread paste around the cpu but to let pressure close it down to provide an even spread with no air bubbles

in this situation should i just go ahead and spread the thinnest layer to cover? or put a rice grain in the middle and let it expand out potentially not covering every millimeter of the IHS

Grain of rice and spread with plastic card covering all the surface of the Heatspreader. That's how I do it and it works fine. Cheers.

Just use a pea sized blob in the middle of the CPU.
*DO NOT SPREAD IT*
Spreading only introduces air bubbles and reduces thermal conductivity.

i know and its why i hate thinking about doing it or the people who actually are willing to create air bubbles in their tim...


but as in that picture, with a heatsink on top, is that cpu safe? is that guy going to burn out his cpu when overclocked since some of the chip has absolutely no tim?

The actual cores (the bits that get hot) are right in the middle of the CPU. Here's a 3770K delidded, you can see the rectangular bit in the middle is where the magic happens. As long as thermal paste covers that area you're good.

i will probably run for a few days or weeks and then remove my waterblock, im just scared i wont be able to set it as good as i did the first time


its hard to hold it over where the screws will go, press it down properly without making all the paste shift AND screwing them into the backplate.... :/

It's not easy, just make sure that when you first lower the waterblock on to the CPU it's as flat as possible.

Like this, you can see it for yourself.

I +1 for rice/pea blob and NOT spreading it out (creates airbubbels)

The meaning of TIM is to fill the microscopic gaps in the material of the chip and the heatsink. Otherwise when you just put the heatsink on the cpu it would work also very well, just here and there those tiny gaps)

i honestly think i did do good, since it took me 3 applications + 3 cleanings to MOUNT the heatsink with the right amount and i did a p in the middle instead of a vertical line

im really scared of trying to do good or better.. im ight just be too nitpicky for a +2-4C difference in a core that also has other factors in it frown.gif

Between spreading (Like a idiot, that was when i was young) and rice pea size, rice pea gave me 5-6C better temps dipping from 68 to low 60s
Spreading is only useful for filling up the gaps in a heatpipe direct touch heatsink not to get any of the actual stuff on the pipes themselves or the IHS
