CORSAIR HYDRO H70 CPU COOLER - IN STOCK (BENCHMARKS INSIDE)

Even a bog standard 2 way pwm splitter will work. You could run 4 vipers off your mobo's cpu fan header without breaking a sweat. They won't come anywhere near 2 amps.

Regarding the Akasa cable. Only 1 connector is 4pin, the other 2 connectors are 3pin but with a space free where the 4th pin would normally go, so all your 4pin vipers will plug in just fine. The primary fan will be the one you have plugged into the 4pin connector on the cable. The motherboard will regulate the speed of this fan and duplicate it accross the other fans. Obviously only 1 fan shows up in the bios or any monitoring software you use.

Ok, I've just ordered one of these cables, if it doesn't work I will find you :)

Right to set up the PWM Splitter -

1.Connect molex to PSU.
2.The one marked motherboard goes to CPU Header.
3.The viper fan thats pushing the air through the cooler connect to the one marked CPU.
4.The viper fan thats pulling the air through the cooler connects to one marked case fan.
5.Set Bios to PWM.
6.The viper fans (2 fans) will be automatically increasing fan speed when under loads up to 1900rpm!


you will love this! trust me and you won't have to find me! :)
 
Thanks for the pointers guys! One thing though...

The pump on the H70/H50 plugs into a fan header (I currently have this plugged into the CPU fan header). Once I get this cable, if I plug it into the CPU header as Bulldog suggests, where should my pump go? I currently have set the CPU fan to run at 100% in the BIOS as this is connected to the pump, the other case fans dont allow you to set a % figure but 'silent', 'normal', 'hyper' modes or 'ignore'.
 
Use the pwr header, its just past the memory slots, check manual if unsure, the pwr header can only give 100% power, and can't be controlled, so ideal for pumps.
 
As above, use the pwr header, or you could connect it direct to the psu via a 3 pin - molex converter, both methods will ensure that it runs 100%.
 
The H50/H70 pump should be always plugged into power 3 pin header next to memory ram (never use pump into the cpu pin header as it was not designed say corsair)

Don't use the pump connect to one of the splitter cable! Just plug into 3 pin power socket on the motherboard.
 
Is the connector for the pump a 3 pin fan type header? Just that any 3 pin fans ive ever had connected to the cpu header on asus boards, (s775 p5q dlx and current p6t dlx v2) have ran at 100% regardless of bios settings, i contacted asus about this and they replied that "fan control for 3 pin fans has been removed from the cpu header".

I have an Asus P6TD Deluxe board in my sig is definitely controlling a 3 pin CPU fan so it seems strange for them to be saying that.

What setting have you selected in bios focus? Does seem a bit strange then, i tried a few different 3 pin fans but all ran at 100%, hence my switch to PWM fans.
 
Just got the new cable through (quick delivery OCUK!) and its made my PC sound less like a jet engine! I didn't realise how loud the two vipers were, I thought it was the Zalman cooler on my 480 GTX :)

The vipers can be a bit loud at full pelt, though not as bad as the sharkoon silent eagle 2000's i had previously. My own two vipers run at 1000-1100 rpm on idle, (very quiet), only ramping up to full speed when cpu temp goes above 60c, use asus ai suite to fine tune the fan speed settings, about the only useful part of that program.:):D
 
That's not the cables fault. You have to enable CPU fan control in the bios. On my EVGA it's automatically PWM control and you need to set upper and lower limits. So I set mine to do 25% below 30 degrees and 100% above 60 degrees. For Asus boards you use something in the bios called SmartFan which does pretty much the same and there is even a smart fan app built into AI Suite that runs in windows and lets you fine tune. Other boards give you the choice between PWM control and standard voltage control.
 
On asus boards its known as qfan, found in hardware monitoring section in bios, once enabled you can select from the profiles, silent, standard and turbo, the app in windows is asus ai suite. Pretty good wee app for fan control, not much use for anything else though.
 
Has anyone got any photo's of this mounted at the rear of the case, would like to see how much room it will take up and if it would obstruct/impeed the airflow to the top exaust fans that i have seen people have in their cases. Also is there much difference in temp between this and the H50.
 
My roof exaust fan is connected to the CPU fan 3 pin connector on my ASUS M4A88TD-V and i can change the speed of that in bios and using qfan. Do they sell 4 pin PWM splitter cables on OcUK?
