Thermal pads which thickness should I buy? (5970 with DD waterblock)

post #1 of 3
Thread Starter 
Hey I am going to order some new thermal pads (hopefully better quality) from frozencpu. Now my question is should I pick up 0.5mm thick? or 1.0mm thick? Now I know that there are some parts that would require me to put double the thermal pads in so I had contact so if I just went with 1.0mm and the block uses 0.5mm would I have any issues?

You should go with the EK 0.5mm pads. Generally waterblocks use either 0.5mm distances or direct contact with thermal grease. If you use 1.0mm where the space is 0.5mm it will decrease the contact on some other part by pushing the waterblock up and decreasing the cooling effectiveness by a lot.

You are probably going to have to experiment unless someone who has already taken the time to do it chimes in. I was thinking of doing the same with my XSPC 5970 block. Getting good core temps with heavy OC's but VRM's get pretty toasty with heavy OC's.

I would get a variety of thicknesses and probably try the thicker more compressible pads first.

The money saved from getting the XSPC @ $80 over the $150 EK block that gets good VRM temps with heavy OC will be paid for with the hassle of taking the block apart several times to find a good thermal pad combination.
