CPU Fan, which one ????

JoeDredd · 12 Jun 2008 at 15:50

Hi all

I have just changed the fan in my TT to a YL D12SM, but I am not fully satisfied with the performance.(stock fan was just too loud & whiney)

So I am looking on fitting something else, I dont mind too much noise as long as it keeps my quad nice and cool. :cool:

I was thinking of the following;

YL D12SH
Scythe Kaze Jyuni 1900RPM Slip Stream 120mm Fan
Noctua NF P12
Delta EFB1212VH

What do you all reckon, and yes I have a fan controller fitted

I thought the fan you have would be more than good enough. What idle/load temps you getting?

But if you don't mind jet engines and just after performance then the Delta is the one to go for.

JoeDredd · 12 Jun 2008 at 16:20

HI greebo

I thought it would be good enough, idle temps are on ave 46, load temps ave 75, which is a bit too hot for me, considering I have lowerd my clock to 3.4 now due to warm ambient temps.

is your Q6600 a B3 ?

Greebo · 12 Jun 2008 at 17:06

Yeah, not good temps them.

If yours is a G0 then I suspect there may be other problems like a high room temperature, bad airflow in case.

If you look at the people using a TT, you can see a 3.5Ghz cpu running at 1.41v which is underload in windows, not bios which only hits 65 degrees after 8 hrs prime95 tft

Another one on 3.4Ghz and 1.31v under load only hits 55 degrees.

So unless you are having to put much, much more volts through, you should be getting better results than you are without changing the fan.

CraigN · 12 Jun 2008 at 17:20

as above are you able to keep it stable with a lower voltage (thats why i asked if it was a B3)

even with my old B3 i could get 3.4 with 1.35v

yate loon fans are good performance/noise fans

virdee2 · 12 Jun 2008 at 18:53

get the delta mate and just adjust it with your fan controller.

it seems to push a ton of air through at top speed so even half that will be a massive amount :-)

CliffyBiro · 12 Jun 2008 at 18:55

For performance/low noise, the Noctua.

Pneumonic · 12 Jun 2008 at 19:46

if you buying a delta bear in mind that the one on OCUK is rated at 24watt/2amp which is beyond what most motherboards and fan controllers will cope with..

I know pneumonic that why I am waiting for sidewinder to get some in stock....unless OCUK would like to expand their range

of deltas

And for info my quad is a G0 step, and I still have 1.4v bios & 1.36v in CPUZ pumping through it, which I think is about average. Setup is as per sig

I may give this a go

JoeDredd · 12 Jun 2008 at 19:56

Right I am going to drop my volts and see if it will be stable at 1.3

I'll send you an email where they can be found

JoeDredd · 12 Jun 2008 at 20:06

rangor can these be used with a fan controller???

I had to up volts to 1.325 in bios for it to post, and running P95 now

I believe it could be bad airflow, hence the reason on changing the fans

I have 1 fan in front of PSU (stock fan), a middle fan attached to middle cage, and 1 fan at rear and 1 fan at top ( all YL D12SM)

TT also has YL D12SM

So come on then how can I improve my airflow :confused:

All my cables are tucked out of the way behind MB tray, so really needing help on this one

JoeDredd · 12 Jun 2008 at 20:16

UPDATE:
P95 after 10 min ave load temps are 76, OC still at 3.4 using 1.325v in bios

virdee2 · 12 Jun 2008 at 23:10

out of interest, what are you using to measure the temps?

on mine, HWmonitor gives hugely different results to Core temp. Obvously i prefer Core temp cos it gives the lower readings :-)

JoeDredd · 13 Jun 2008 at 11:41

Virdee I am using coretemp, well I am prime stable with 1.325v in bios and idle temps have dropped to an ave of 42 but load temps are still 73 ave.
So I will get some better shifting fans when in stock and I may fit 6 fans in total so 2 in front, + 1 on mid cage, as well as 2 exhaust fans & 1 for CPU.
