advice on what should provide best cooling + lowest noise.

post #1 of 4
Thread Starter 
I have a Rosewill Gear X3 which has space for 2 top exhaust 120mm, 1 rear exhast 120mm, 1 x 140mm front bottom intake and 2 side panel 120mm slots.

I plan to purchase 3 yate loon D12SL 120mm fans and place them as 2 top exhaust + 1 rear exhaust and leave the 140mm stock fan where it is. Then is my question.

What should provide the least noise yet the best cooling on my TRUE Black which is mounted horizontal (with air flow from potential fan/s going blowing upwards). My options are:

1 x 120mm Yate Loon D12SH pushing air through the TRUE upwards

or

2x 120mm Yate Loon D12SM pushing + pulling air through the TRUE upwards

The D12SH is rated as 40db around that, and the D12SM's are rated at 33db each. Using a formula I found online the 2 D12SM's would put out about 36db together while the D12SH would be 40db by itself, but which would provide better cooling because of cfm/static pressure. Maybe I'm worrying too much and should just get the cheapest of the two.

Any opinions would be helpful, thanks!

I would go with 2 low speed Yates in push pull on your TRUE. Mediums will only give 1-2 C better temps and be more noticeable in noise. And the high speed Yate is a bit noisy to live with if you are susceptible to noise. The gains from push pull fall off quite a bit as you get to higher cfm fans on the TRUE. They are still there but don't make as big a difference as the cfm and static pressure go up.

As for buying the Yates, order the ones from Sidewinder or Petras Tech Shop as they are bought directly from Yate Loon. Also, Jab-tech is selling 2 different models of Yate Loon fans. The ones to get in the low and medium speed models from them are the ones labeled as direct from Yate Loon. The others, while cheaper, use a smaller motor and don't move the air the direct bought models do. Pricing on the good Yates is comparable at all 3 places, but PTS and Jab-tech drop the price to $5 a fan with 4 fan orders.

Thanks for the comments. I kinda am still leaning towards at the minimum 2 D12SM's in push/pull because I want my cooling to be decent enough for a potential decent overclock with Bulldozer if it ever comes out.

I tried push/pull with 2 sunon fan's that I have (versus the one that I'm using right now to achieve 3.8ghz while folding @ 35C with around 20C ambient), and I didn't notice much of a difference but the noise is unbearable. The exact fans I have are:

120mm Sunon KD1212PTB3-6A 2400rpm 69cfm 35.5db

They put out good cfm with good pressure but wow they are loud. They are also ball bearing so they have no problem with any orientation. That's why I'm leaning towards the medium or high speed Yate Loon since they are sleeve bearing and I've read time and time again that they will lose some cfm/pressure when mounted pushing air vertically.

front = 140mm intake
bottom side panel = 140mm intake if it fits, 120mm intake if it doesn't. also need to add some sort of air filter on the outside.

top side panel = duct taped to reduce pressure bleed. no fan here cuz of cpu cooler height.

top 2 fan mount = intake and maybe filters if it needs it.

rear exhaust fan mount = exhaust (no need for filter since it's exhaust)

CPU cooler oriented so it blows towards the rear exhaust fan. number of fans on the true depends on how heavy you want to OC.

with this configuration, you'll have a positive pressure case which will help cool down everything while still having all intake sources filtered.

the only thing you cant do is to place the case under a desk or in a semi enclosed space where the hot air exhaust from the powersupply/GPU/CPU is pulled back into the case by the side panel fan or the top intake fans.
