How will adding a full motherboard block affect temps?

post #1 of 4
Thread Starter 
I am already water cooling two gtx 480's and my intel i 930 at 4Ghz, cards at stock. I have a 240mm and 360mm rad with medium yate loons. I get decent temps. The cards never go over 45C and the cpu tops out at low 60's. I am going to change the medium yate loons for 3000rpm gentle typhoons. And I want to add a full water block cover for my mobo so what temp differences do you think will occur?

May increase cpu and gpu temps a bit because of the extra heat and constriction. But, from the gains from the block will be minimal as it's mostly for appearance

Watch out for restriction, MB blocks can be the single most restrictive part in an entire loop, sometimes accounting for many times more restriction than an average CPU block.

As far as heat goes, it depends how much. On a 240 rad, 50 watts of heat can relate to 1-3 degrees depending on fans.

Motherboard blocks are mostly for aesthetics anyway. They don't offer much of an increase. In my opinion, they're not worth the money - Martinm210 summed up the consequences of getting one if you so desire.
