more watercooling questions :)

[bigjimmyauk]

ok could have questions today

2x240 rads or a single 360

and i have a HAF 932 so if i had a triple rad on the top would it need to bring air in from the outside or use the air from inside the case and blow out just like the stock cooling?

Correct me If I'm wrong, but shouldn't the rad/top fans be exhausting air?

Hot air rises etc etc, Otherwise it'd just be blowing it onto other components.

You can exhaust air from the case through a radiator. Nothing wrong with that.

Remember that with air-cooling all the components heat the air in the case. With water-cooling all the water-cooled components vent their heat into the water and to the radiator so the case temperature will be lower than with air-cooling.

If you water-cool everything the case temperature will be close to ambient.

Knock down the text size on your sig, before a mod see's it

in 90% of single loops a tripple will be better that two doubles.
but if the 'why' you are watercooling is bling or max oc possable (using noisy fans)
then two doubles. As slightly greater surface but with increased restriction.

As to air flow, it back to the why. (quote for martin's liquid lab tests)

Push Vs Pull - This depends on fan speed/power. The high speed fans at 2000RPM with a 38mm fan thickness provided the best performance in a push condition. The slow speed fans with 1350RPM with a 25mm fan thickness provided the best performance in a pull condition. I would estimate that performance line is likely to cross in the 1500-1700RPM range where they are equal. So.... slow speed = pull, high speed = push, medium speed = it doesn't really matter.

First decision to make is why are you watercooling?
As there are only three answers omho - bling(inc ocd temp symdrome) / benchmarking / silence
and each have a very different setup.

Air cooling is so good these days that many longterm watercooling fanboys have sold up their loops and returned to air.
air is less hassle, less expensive, lighter, lower maintainance, easier to swap out hardware, lower risk of hardware damage, etc.

If i remember correctly you want to watercool cpu and add the gpu later? Definately exhaust the air out the case otherwise you'll be filling your case with a lot of warm air, which wont be great for any non watercooled components.

Stick with the tripple, will be plenty to cool a cpu/gpu loop and will keep it simpler for the build.

My main reasons were to keep temps the same or lower but overall have a quiter system my load temps under prime on air cooling reach about 50 degrees on full fan speed using a baram in push pull, I'm hoping to lower this to the low 40's but with a quiter system.

The stock HAF 932 fans shift bucket loads of air even at slow speeds and they are very quiet biggest culprit for noise tho is the 230mm front fan blowing through the HDD bays which i think creates a lot of random air paths which makes it rather noisy by which i mean a strange humming sound(resonating sound i dunno)

i'm actually consider mounting the HDD's in the 5.25 bays and drilling the rivets out the HDD cage to make a cleaner air path also gives me room for a pump and res if i do decide to water cool (which i think i am)

The problem with air cooling is that on AM3 boards your really limited when it comes to big coolers especially when they start fouling the Ram slots(dimms)
