do i need to put termal gel between the processor and the water block????

yes.. u should know the function... right?

Yes of course you do... just the same like any heatsink

new to tiz water cooling system tats y dunno have 2 put the termal gel or not....

its normally called TIM or thermalpaste bro .
and yes put it cause it has the same function for any heatsink .
to give better connective area .
thus better heat transfer .

can put any other thing 2 replace the termalpaste????

erm, heard ppl used toothpaste before .
and also margerine i think .
but not sure it's safe or not /

margerine???
it will melt easily rite?????

Yup, that's why butter or margarine is totally bullshit but personally i tested toothpaste before
Tried 2 hours end up replaced with good performance TIM

zzzz.....i put termalpaste ady...
