Hey guys, great forum.

I had a couple of quick questions on rads: How much clearance do I need on either side, (fan side/grill side)? What’s the gain from going push-pull? And finally… I’ll be running two loops, a cpu loop for an oc’d i7 and a sli gpu loop. I was going to run a 120.3 in each, but I was wondering if it would make sense to also add a 120.2 to each and run two mult-rad loops. Would the return on the extra 120.2’s be noticeable... would the extra restriction be a problem?

TIA

Looks like your doing your homework. Good! Each side of the rad should have at least an inch after the fan for air flow. Add the rad thickness, standard 25mm fan thickness and a grill. Might want to add 1/4" for a gasket.

Push pull really helps the high FPI/really thick rads that NEED that. You buy the right rad you don't need push/pull for your planned setup.

Might want to ask these questions at some busier forums with lots of watercoolers. Few active ones here.

A 120x3 rad for each loop is fine, seperate pumps and reses. Your Delta T would show little improvement. Seen this post yet?

Thanks Conundrum.

Yea, as with any investment of time/money, I've found due diligence often trumps impetuousness, (research is our friend). Anyways, I'll reg and post to eocf, xsf and ocf, though I'm pretty sure you've answered my questions.

Yea, I stumbled onto a few of those posts/forums a little while back... and found the buying guide on eocf to be quite nice... http://forums.extremeoverclocking.com/showthread.php?t=282232]... as well as the gilgamesh review you link in your std cut'n paste. I'll definitely hit your test links next... speaking of which, it appears your "http://translate.google.com/transl" one's 404.

Thanks again.

It's broke? ahh too bad. I'll check it and take it out then if so. Kinda old, but was a good review with important learning points.

EDIT: Just worked for me....

Gilamesh review is really new, the author is a good guy we see on OC Forums a lot. Was a pleasure to help him with input.

And thanks for the feedback, we get way to few of these.
