Sorry if this is in the wrong section. I am going to be fitting my upgrade parts to my rig over the weekend and I am going to be ordering the last of the stuff on friday. I will be fitting a cpu waterblock and graphics cards waterblocks. Can I get some suggestions on what compound to use as I lost my tube of arctic silver. I also read that a non conductive tim is better to use on graphics cards. Is it worth buying two kinds one for my cpu block and one for my gpu blocks. Thanks for any advice.
