Apache dissapointment

Appache's, Typhoons, Vipers, Harriers anyone?

I think the F-22 is quieter though. There is also the Rafael to consider.

I got the Scythe Gentle Typhoon's - 1450RPM (Out of the 3 models listed above) - They perform pretty darn well! BUT I just realised they are only 3 PIN - so I can't seem to control them with the Akasa 3-way PWM splitter I had :(

Doesn't matter me wants an Aquaero - any excuse lol

Your board supports DC as well as PWM... you can still control the fan speeds via DC. Or are you referring to software for fan control?
 
Ive only ever used PWM, As I have an ALC ECO I cant use speed control on the fan headers but on the CPU fan header I can.

To ask a silly question, how do you control via DC?
 
If your board supports it you switch the fan type from PWM to DC. I recently replaced all my fans to PWM and I honestly can't tell the difference. As I ran some other fans via DC.

What's your idle/load temps with the apaches? and do you have the motherboard slow them down at all?

It's for those that don't have PWM fans, 3 pin fans. DC adjusts it by voltage so you don't have fans at full blast all the time. It'll raise the fan speed by voltage as the CPU heat rises. Just as PWM. I honestly can't tell the difference between PWM and DC having used DC for so long.
 
ahhh i see.

So, could u use 3 pin fans on the akasa fan splitter but set CPU header to DC and it controll both fans?
 
I tried that guys - Set it to DC instead of PWM (same as above screenie) but it wouldn't throttle down my scythes using the Akasa splitter :(

will reply to your email soon Angel_Rex - once I have chance to defo check out that second apache ;)
 
ps - stick with apaches - they seem to be quieter than the scythes.
need to get this akasa thingy working - not sure why it don't allow to throttle 3 pin fans....

That would only work if you daisy chain 3 pin fans. You can't mix and match 4 pin PWM and 3 pin fans hoping they'll throttle. It's one or the other. That was one of the reasons I replaced all my 3 pin fans for PWM.

I doubt the motherboard could detect the 3 pin fans with the 4 pin PWM splitter? hence it doesn't know what to do with them so it runs at full speed. The only way it would work is a separate 3 pin splitter. Thats what I use to run since I only had 3 pin fans.

It's a real pity the Sharkoon 2000rpm fans are not PWM. :/ I loved those fans.
 
I would try ONE 3 pin fan on the CPU 4 pin header and see if it will throttle it down using DC

According to this user fan round up, http://forums.overclockers.co.uk/showthread.php?t=18272087, it seems the apache is as good as the 1850rpm scythe GT.

I want to try and keep my case as quiet as possible :)

I still cant decide between the apache or GT. I need 3 new case fans, front intake, side intake and top exhaust.

ATM I have my eco alc on the rear fan mount with push/pull config as intake.

This is basically drawing cold air from the outside which is then vented through the top of the case. Seems to work really well.

The thing I have to consider is - I dont want to faf with fan controllers (also not got that much to spend) so if I have to run the front side and top all at full rpm i want them as silent as poss.

The MOST annoying fan in my case the the one on the ATi4850, it gives a real whining noise :s catalyst control centre really wont reduce the fan speed/noise :s

hey mate, I'm not mixing any fans - I'm only using the three Scythe GT's all connected to the Akasa splitter - which in turn is connected directly to the mainboard CPU connector.

This same setup used to work perfectly with the Apaches (as they are 4 pin PWM fans). I'm just pitting it down to the fact I'm now using 3-pin fans with a 4-pin splitter. tbh i'm not that bothered as I REALLY wants the aquaero controller ;)

One thing I have noted about the Akasa splitter is that out of four possible pins theres only three - one is missing. This is the third pin out of the four (The third pin on a 3 pin fan).

@@Angel_Rex - stick with the Apaches mate - They are actually case fans as opposed to CPU fans - so are much suited to booting air around a case (and I mean literally boot!) - Plus they are definately quieter than the GT's - if noise levels are what you are trying to reduce.

The GT's are better for me as I am using them on a Rad (Less static pressure) - I can tell as they cool it better, but are ever so slightly noisier than the Apaches.

Now to convince the missus I REALLY REALLY REALLY need the aquaero - lol :D

So prob sticking with the apache would be best over the 1450rpm typhoon.

Ignore the apache's "Max static air pressure 26.40 mm-H2O" as this is totally wrong and ocuk have been told about this mistake since the apache's first came out, it should be 2.64 mm-H20 & not 26.40 mm-H20.
 
lol errrr - Me know nuttin bowt static pressure lol.

I was gunna blame Amidar if it all went wrong :P lol

Numpty here has just realised why three pin fans don't throttle down using the Akasa splitter - its connected to a molex adapter and hence gets its power from my PSU not the motherboard - duh!

@@Amidar - I'm using the GT's to push air through my rad - would I be better off getting setting them in Pull as opposed to push - and or use fan shrouds?

Theres something wierd going on - The first GT I have (closest to drive bays) is making more noise than the others - I think theres something up with my Rad or its fan fittings which is probably the reason two out of three of my apaches started becoming noisy (I swapped them at some point).

grrr - I'm losing patience with this whole darn watercooling - don't get me wrong - its awesome for reducing noise levels under load (but that happens rarely), problem now is keeping noise super low when idling

It keeps my 5850's at 31Degrees C, but in terms of CPU - theres only 3-5 Degrees C difference over my H50 :(
 
I'm using 1850 Gt's but undervolted to 7v,the radiator i'm using is BI SR1-360 which has deep shroud built into one side of the radiator & i have fitted the fans to this side (pushing air).

Now i'm only cooling my cpu, with my previous cooler (Meghalems) it would idle at 38-40c i7 920 @ 4.00Ghz & load at 75-78c when running intel burn test.With a koolance 370 block & the above radiator it idles @ 33-35c but load is now down to 60-61 & also the weather has warmed up a lot later aswell.

I know the apache is 2.64 static pressure :)

I'm trying to decide which fan would be best for my case and ECO rad.

Im not fussed by a few 'C. I want the best cfm airflow to noise (as does everyone)^^

If the apache are quieter than the 1450rpm GT then ill stick with the apache, if the GT would be better, ill go for those on my ECO & in the case :D
