space between fan and rad?

Hi all

I recently bought the Thermaltake Aquarius III watercooler for my first adventures into water cooling. I am VERY happy with it.

Opening the unit up I noticed there is about a 1/2" gap (or more) between the fan and the radiator. Is this done on purpose? Maybe to make the unit quieter?

Will blocking off that gap get me better cooling capabilities?
 
Well if there is already a half inch gap between the two it may help a bit by closing it off. Mounting a fan directly on a rad is kinda dumb, as you lose a lot of airflow....whether its a blow or suck fan. Spacing it out and/or installing a shroud greatly increases the effectiveness of that fan on the rad.....close it off. :D
 
Its generally a good idea to have some spacing, Ive heard 2" being mentioned as a good distance to remove the dead spot of air.

DEFINITELY shroud it. U want to make sure all the air getting pulled throiugh the fan is coming through the rad. Either pulling or pushing a shroud makes sure your getting the most air flow through the rad as possible.

Yep.....and push is always better then pull if you've only got one fan.
 
I beg to differ, pulling gives you better air distrabution through the whole radiatornot just the area where the fan is pushing air throughand the block air is redirected causing turbulance and interrupting air flow .
 
Check it out for yourself then.....the majority has spoken, and I've personally never seen better results from a single fan setup that's blowing as opposed to sucking through the rad.
 
Well, the guys at overclocking .com, procooling.com and the thermal engineers at Delphi thermal engineering House of help forums, all say pulling is better. And from my reviewing of numorus water cooling solutions show that pulling is better. But anyway, to eaches own so they say. You can have you're push and I'll have my fans pull.
 
I normally set up all of my cores with the fans pulling air thru the core - the shrouds have a minimum standoff of 1"

That's alright....it still looks bloody cool for those of us that're still running our systems on air. However, in just over a month I'll have my Prometia Mach1 to make you all drool. ;) :D

my cascade phase change might be finished in a month. :p

I'm on the road to -100 C...or blowing the house up - whichever comes first. :)
 
Thanks for all the replies guys - but I wasn't asking if I should have the fan push or pull. How'd we get on THAT topic????

I will see about building a shroud around the fan gap then.
 
Sorry about the topic change................ :) Seems to happen alot when you talk about shrouds..................... :eek: Anyway, just filling in the gap will help you alot by making the fan pull or push all the air through the radiator and not through the open spaces on the sides.

Nice stuff dude. I'm not quite there yet.....but I'll be getting the Prometia re-gassed with r507 or something to give it a bit of a boost. Beyond that I'll have to look at what I wanna do, cus whatever it is, I want my cooling to be completely mobile...along with the rest of my computer. While a lot of those cascade setups are nice.....it's not usually something you can just pick up and leave the house with.....and this is my only computer, so the cooling has to be able to LAN with me.

Man, if the thing's weren't so fricken heavy I'd look at down the road putting a second Prometia attached to the top of the case, so that I could have one on teh video card, and one of the cpu.....but that's as far as I might ever go. By then, unless we're comPLETELY around the thermal throttling at sub-zero temps with the 6800's I'll probly end up switching to an X800XT.....but that's only if I do get the second Prometia for the card.....cus freezing 6800's is just so much of a hassle.
