Is MCT-5 coolant okay to use with a restrictive CPU block? Tags: Heatsinks CPUs Overclocking Last response: October 1, 2006 7:41 AM in Overclocking Share antand September 30, 2006 12:32:46 AM I have 2 bottles of MCT-5 coolant and wanted to get some opinions on using this coolant with a restrictive block like the Aquaextreme MP-05 LE?

Have not flushed the system with this stuff. :wink: phreejak September 30, 2006 11:51:27 AM It's not the coolant you would have to worry about when using a restrictive water block - it's the tubing ID size and the pump that would have the most influence.

Get the answer antand September 30, 2006 12:59:50 PM I've got the DD D-5 pump and using 1/2" ID tubing so I think that part should be okay. I just didn't know if the viscosity of it would matter. I'm guessing since it's non-conductive there aren't any little particles in it to get clogged in the jets. phreejak September 30, 2006 1:09:57 PM Good pump (same one I use), good tubing (same ID I use)... You'll be fine... shawnlizzle =] October 1, 2006 1:33:26 AM dont' put too much, you don't even need the additive gomerpile October 1, 2006 7:41:34 AM additives are needed, about 3 months time he will have to flush out the system do to slime clogging the pump Can't find your answer ?
