WC Fans and general advice

Admiral Huddy · 26 Mar 2013 at 16:05

I keep going round in circles here..

Can anyone recommend or suggest 120mm fans that push a decent air flow at very low noise for a triple rad.

Thanks

edit..

Proposed setup

already got:
Swiftech MCR320-QP-K Triple 120mm
EK Supremacy CPU Waterblock

to buy :

XSPC Laing 18W DDC-Pump 12V DDC 3.25 - ULTRA PERFROMANCE - 900lph XSPC Acrylic Top for Laing DDC - out of stock

XSPC Dual 5.25” Bay Reservoir (Alu Front)
XSPC RS120 120mm Radiator - Black
8 x Bitspower Premium G1/4" Black Matte High Flow 7/16" ID (5/8" OD) Compression Fitting
EK-EKoolants UV Blue
XSPC HighFlex Hose 7/16" ID, 5/8" OD, 15.9/11.1mm, 2m, Blue/UV Blue

res >>> pump >> triple rad >> cpu block >> single rad >>> res

Is the single rad an over kill? I thought it would reduce the ambient temperature in the res before going to the triple.

Also, any got any experience of the Laing 18w? 3.25. Noisy?

Everything I have read says Scythe Gentle Typhoons for pretty much any WC use. Great static pressure and low rpm/noise.

OCD-OC · 26 Mar 2013 at 16:07

yup, Scythe Gentle Typhoons got eh low RPM ones in my rig, can't even hear them

the PSU is louder

single CPU on a triple rad?
you could go with GT's if you really want to spend £45, or you can use XSPC 1200 or 1450RPM fans for £5-6 each

either will be over specced for a triple rad / single CPU loop

Admiral Huddy · 26 Mar 2013 at 16:26

These one?

I've already got the triple from when i coooled the VGA in the same loop but I can't be ***** to WC cards anymore. To much hassle when upgrading. I get quite disappointing temps on my IB so I thought a combo of de-lidding and another rad might help.

I've just been testing a couple of Scythe GT's on a Monsta rad and I'd say hell to the yeah for low noise and airflow

The same goes for vs tests on a K2 cpu cooler.

Scythe GT
37cfm : 1150 rpm, 26db

Scythe Kaze Jyuni 1200RPM Slipstream 120mm
68cfm @ 1200 rpm, 24db

The Kaze Jyuni's look better or am i missing some here?

The Kaze's will flow more air if their sat outside the case blowing into an airflow meter, however the GT's will push/pull more when bolted to a radiator and forced to overcome the resistance involved.

NB, your noise stats for the 1150RPM GT are wrong, its supposed to be 16 dBA.

Admiral Huddy · 26 Mar 2013 at 16:47

So you would recommend the GTs over Scythe;s?

Spec i got from the shop :

- Manufacturered in Japan
- Only 21.0 dB(A) at 1150 RPM
- Weight 200 g
- Dimensions 119 x 119 x 25 mm
- Air volume at full speed (12V), CFM ±10% 37.1
- Noise level at full speed (12V), dB(A) 26.0
- Fan speed at full speed (12V), RPM ±10% 1150
- Bearing Type Double Ball Bearing
- MTBF 100,000 hour at 35°C or 60,000 hours at 60°C
- Accessories 4-pin Molex Adapter, 4x Screws

Where are you getting the air pressure stats?

Uncle Petey · 26 Mar 2013 at 16:57

You can't go wrong with the GT's, Huddy.

those with a fan controller could be a winner

pgi947 · 26 Mar 2013 at 17:16

^They are good, and do move some air, I have 6 on my two 360's. At full speed though they do belt out some noise so a fan controller is essential if using them. Silent up to around 1000-12000 rpm.

High Budget = GT's, Corsair SP's
Med Budget = Yate Loon/XSPC
Low Budget = Golf III

Ideally you'll want a controller what ever you choose.

mjones1 · 26 Mar 2013 at 17:39

I have had 2 different DDC 18w pumps and both have been quite loud. Alternatively you could use some 7v or 5v adapters, I have some of them golf III's (sharkoon silent eagle) 1000rpm version and found I had to undervolt them to about 7v to keep them quiet or I'm a silent nut.

Something Else · 26 Mar 2013 at 17:55

ive got a couple of those oem golf fans now.

at £3 a fan they are a true bargin!

ive tested mine on a fan controller and even at min speed they are literally silent, cannot hear them over a 120mm akasa apache. they shift a good amount of air at min speed, you can still feel it through the radiators.

im gonna buy a couple more of them and just use them for the radiators. serious bargin

Triple pack of them for £8. https://www.overclockers.co.uk/showproduct.php?prodid=BU-036-TL

Something Else · 26 Mar 2013 at 21:22

If i took into account the performance, noise and cost then these are the best fans ive bought. i dont think they look bad either!

Scythes own page: http://www.scythe-eu.com/en/products/fans/gentle-typhoon-120-mm.html

1,150 rpm: 0.034 A - 16 dBA - 63 m³/h

Personally I would recommend the GT's over the Kaze's, even though im currently running three 800RPM Kazes on my rad lol (If 800RPM GT's were redily available in this ocuntry I would snap up three of them).

OptimaLnrg · 26 Mar 2013 at 21:47

I would ignore all of the stats any manufacturer puts out about their fans because they are nearly 100% utter B.S.

Here are some good rad fans:

noctua nf-p12/f12
silverstone AP's
scythe gt's
corsir sp's
noiseblocker e-loops (specific models)

Interesting, I was under impression the pumps were quite quiete.

Thanks Ubersonic - I am still confussed as why a fan almost double the CFM andair pressure isn't as effective as the lessor one?

Sythe Kaze Jyuni SY1225SL12M K24,00 dBA / 68,54 CFM = 117 m³/h / DC12 V / 0,26 A (1,200 rpm Version)

Scythe GentleTyphoon 120 D1225C12B3AP-13 (1,150 rpm) 1,150 rpm: 0.034 A - 16 dBA - 63 m³/h

reason I'm asking is i already have 3 Jyuni's on the triple rad.. but wondering if i could improve.

mjones1 · 27 Mar 2013 at 10:48

It's a mixed bang of opinions, you need to mount it on some sort of foam/ decouple them for them to be quiet. Personally I would just go with the D5 pump has they tend to run quieter, can control the speed on the vario model.
