**Updated: Attached pic of Venom.**

Hey all,

Last night I managed to upgrade to the following CPU cooler on my rig:

Akasa AK-CCX-4002HP Venom CPU Cooler
http://www.overclockers.co.uk/showproduct.php?prodid=HS-072-AK&groupid=701&catid=57&subcat=1395

I also bought a second fan with it:

Akasa AK-FN059 120mm Ultra Quiet Viper Cool Fan
http://www.overclockers.co.uk/showproduct.php?prodid=FG-059-AK

The install went nice and easy compared to most fans which I was impressed with and it made a lot of difference in my CPU temps from my previous Zalman CNPS9900-LED cooler.

So I had one fan blowing air in and the second fan blowing air out as advised.

I presume there are others that have this fan and I was wondering if you guys have fan controllers installed in your rigs to control the speed / noise level?

The fans are great but the only downside is they do seem quite loud. although its hard to balance between being cool and being loud I guess. I have an Asus Maxmimus Formula SE board and I have the Q-Fan utility have the CPU profile to "silent" too.

I may just deal with how they are as the temps seem okay but was wondering what most people usually have as a setup for fan controling.

Cheers guys.

Edit: I did notice OC sell some fan controllers here but never got any yet: http://www.overclockers.co.uk/productlist.php?groupid=701&catid=1428&sortby=priceAsc&subid=1429

be careful mate if I were you cos I brought fan controller myself but it only work with any fans that had 3 pin on it as it will not work with my Akasa Apache Brown Super Silent 120mm Fan - 4 Pin PWM as I had to use this 1 fan into cpu pin header to use PWM in the bios but 2nd fan (same make and model) had to use full speed as cannot use fan controller (only support 3 pin only) and cannot use any spare 4 pin header on motherboard.
 
This is a better page for fan controllers. http://www.overclockers.co.uk/productlist.php?groupid=701&catid=57&subid=189&sortby=priceAsc

Using the Scythe Kaze Master and it allows either 3 or 4-pin fans to be controlled. Got an Akasa Apache connected to it and it works fine. Wouldn't suprise me though that the Venoms are loud spinning at 1900rpm :eek:

Unless both your venoms are connected to 4-pin sockets on your mobo, only one of them is being controlled by Q-fan (Most mobos only have one 4-pin for the cpu fan). Another method is to use this PWM splitter cable http://www.overclockers.co.uk/showproduct.php?prodid=CB-031-AK which allows both fans to therefore be controlled.
 
liquidex - I had these PWM splitter cable (but i only can see 2 x case fan with a 3 pin on it with a label mark on it as I had put 2 x Apache 1900RPM 4 pin PWM on it) and plug the 4 pin into motherboard cpu pin header (with a label connect to motherboard) and both fans ran at 1100rpm and 1900rpm ? doesn't work with 2 x 1100rpm ? how to do it ?
 
Thats strange. Tbh I don't use one but its been recommended loads on these forums.

From the pics you need one fan connected to the one with 4 wires coming out of it, labelled cpu fan. Then I would put your other Apache onto one of the 3 pins labelled case fans. If you already did this then I'm lost.
 
Xion, im assuming you want to use two akasa vipers on your cooler. If so, this is the wee cable you need mate.

This will allow speed control of upto 3 PWM fans, such as vipers from your single motherboard cpu header. Power comes direct from the psu, therefore no strain is placed on the motherboard. Ive found this to be a very tidy, effective way of running PWM fans, (upto 3 at a time), currently runs two akasa vipers on my TRUE black.

setter, do you mean you can use 2 x akasa vipers (1900rpm) fans on the cpu cooler and one 4 pin go into cpu pin header for PWM control at the bios and where can you put another 4 pin (for PWM) are you put 2 x 4 pins into these 2 x case fan as a white label marked on it and use power supply to plug in without the need of cpu pin header but if use the power supply how can the 2 x vipers can reduce speed fan from 1900rpm to 1100rpm at the same time ?
Can you please kindly show me a picture what did you do exactly with the correct way of these splitter cable. I can't get my head round it. Thanks setter.
 
Right to set up the PWM Splitter -

1.Connect molex to PSU.
2.The one marked motherbroad goes to CPU Header.
3.The fan thats pushing the air through the cooler connect to the one marked CPU.
4.The fan thats pulling the air through the cooler connects to one marked case fan.
5.Set Bios to PWM.

Hope this helps. :)

Thanks a lot for the feedback and advise so far guys!

Well I turned my PC on this morning, and its a lot cooler than last night room temp, and the fans were pretty quiet for around 25 mins then started to get louder again and stay like that, I remember before they would go loud under load then go back down when i'm doing less on the PC.

Real Temp is showing 33 35 33 33

Here is a pic of the rig at the moment (Its missing its sound card at the moment)

So the case I am using there is a Lian Li Armorsuit Mid Tower, which has 3 fans on the front pulling air into the case, which are very quiet, and a fan at the top of the case pulling air out which is quiet too.

I think I have chosen the correct way for the airflow for my Venom, as the PSU is right above it and I didn't want to be blowing air into that fan which is blowing air down. So both of the fans on the Venom are blowing down. The one nearest to the PSU is connected into pin labeled "CPU_FAN" and the other into "CHA_FAN1"

That other cooler is an Antec SpotCool System Cooler:

I have this set to Low right now, its not bad on either Mid or Low, but its up to you where you point it and I decided to point it towards RAM / back of GTX. Thats a stupidly long BFG 8800GTX there by the way.

Does everything seem normal apart from me putting the 2nd fan into CHA_FAN1 then?

I have placed the Q-Fan settings on AI Suite to: CPU Q-FAN - Silent , Chassis Q-FAN - 60% (Might put this back on Auto...)

Thanks a lot everyone!

Edit: Oh wait I see...I might be wrong but, because the 2nd fan is in CHA_FAN1, is Q-FAN adjusting the Chassis fan speed of that fan up and down because of a target temp thats set (BIOS has a target temp), so the main noise might be comming from just that bottom fan connected in CHA_FAN1.

PSU fans generally pull air into the power supply so atm I think you are creating a dead zone between the top of the venom and and the PSU. Would rotate your cooler 180 degrees.

Also unless you have switched the fan on the rear of the case to an intake as stated in your pic, it would be default set up to extract air from the case (blowing the opposite the direction to the arrow you have).

EDIT. If you have the chassis q-fan set at 60% then its running at a constant speed.

Set rear case fan to extract air, rotate Venom 90 degrees to the right -

Rear Case Fan <- <-extracting air <- <- Fan Pull/Venom/fan Push <- <- Air Flow

Get A PWM Splitter Far Better.
Right to set up the PWM Splitter -

1.Connect molex to PSU.
2.The one marked motherbroad goes to CPU Header.
3.The fan thats pushing the air through the cooler connect to the one marked CPU.
4.The fan thats pulling the air through the cooler connects to one marked case fan.
5.Set Bios to PWM.
 
Argh damn..

OLDPHART what you said about the 90 degrees I was going to do that in the first place but went with what I had above which was totally fail.

liquidex - Damn my understanding of the PSU fan was wrong then, cheers for letting me know, I just put a small bit of paper next to the rear fan and yeah there is more air coming out the back to it is blowing out the case.

I may have to go through the nightmare of turning that CPU cooler 90 degrees then :) I just hope I don't need to upgrade RAM as the fan will cover the RAM if i turn it 90 degrees.

:) It now work! Thanks oldphart. I done the wrong way.
 
Ok done.

That didn't take as long as i expected, this CPU fan is really user friendly to install I'm impressed. It just took a while getting the fan closest to the rear of the PC back on as I didn't want to remove the mobo from the case. Luckily I have small hands and fingers so i found my way into an awkward position to get both fans back on the Venom.

When i took the CPU fan out, the arctic silver had spread and was very very thin, i put a very small line of the silver across the CPU (as its a Q6600 Quad) and placed the cooler back down and screwed into place. I hope the surface between the cooler and the CPU is okay!

The fans are now blowing air as OLDPHART suggested.

Real temp is showing: 28 31 28 28 although the case is open. I'm just hoping the silver is on okay I always get paranoid about that.

OLDPHART / setter I ordered one of these:

Should come on tuesday with my new sound card too.
 
Ok just adjusted that SpotCool fan so its pointing at the RAM area. I was worried before the CPU fans would cover the RAM but they didn't, they just touch the edge of the ram slots so all is good.

Got the side back on and everything now, and glad I did that. Just wish I pointed them that way in the first place! Would have saved me having to lift up the cooler from the CPU and mess up the arctic silver :(

RealTemp now showing: 33 35 33 33

Thanks everyone who replied, I always learn loads of these forums :)

Just awaiting the cables on Tuesday.
 
bulldog147 I was going to reply saying are these temps okay :)

I'm always really paranoid about CPU temps, I keep thinking there might be something wrong with the arctic silver spread and things are not perfect! But I guess whats done is done, I will leave it as it is.

Cheers!

No, trust me, your temp idle is quite excellent indeed as I wish I had below 35C but of course it depend on the case airflow and room temperature that matter!

Your 4.20Ghz overclock with vcore of 1.30v could be under 77C with that idle temperature!
 
Thanks. At the moment my Q6600 is still at its default 2.4, and I was planning to get it to 3 or so instead of buying a new processor (which I was firstly planning on doing). Thats why I thought I would get this CPU fan upgrade done first.

I've never overclocked before, and don't really want to mess it up, so I will probably get a mate to help out with that...

I use to have Intel Quad Core Q6600 before sold it to my mate Tim. It a very good processor chip with 4 cores and 4 threads with stock speed of 2.40Ghz. That's why it as idle below 35 as at first I thought you were using Intel i7 920 do. :o
