Can anyone explain how to mount the corsair c70 window from mnpctech? It came with a bunch of rubber grommets but do i need to use them?

Wouldn't this have an effect on performance? Especially if the water inside the radiators aren't being cooled after heavy loads?

I have all pwm fans in my case. I bought them thinking the 3 chassis fan headers on the motherboard were PWM as indicated on the board and in the owners manual, but this information is incorrect. I've since purchased two 3-way PWM splitters that get power from the PSU molex and use the signal from the CPU fan to control fan speed. I was using ASUS Fan Xpert until a couple of days ago where I switched to SpeedFan which is superior but more difficult to configure. At the moment I am running 4 120mm fans off the motherboard headers using the voltage control and 2 140mm fans, 1 120mm fan and the cpu cooler fan off the CPU header. I set "rules" in speedfan such that if the GPUs get hot, both the case and CPU fans increase speed, and if the CPU gets hot, both the case and CPU fans increase speed. I'm really stoked with how the software keeps up with GPU temps so I don't have to adjust the fan profile in FanXpert anymore. There is some discussion as to how many fans you can drive off one PWM signal but I had as many as 6 fans controlled by using a Y splitter for push/pull on the CPU cooler and the 3 PWM splitters "daisy chain" to run 4 other case fans. Now I'm only air cooled but I think this would work for watercooling radiator fans as well.

I don't have the window but if you look closely the original window then you will see that bits of the window have raised bits acting as a built in grommet, so essentially so you can use the original screws with the new window then spacers are needed.

Hmmm I will investigate before buying a fan controller then, thanks!

Hey Gavush. Thank you so much for the informative post. I just read your thread in regards to your Asus motherboard problems. What a runaround. lol

I am using a Maximus V Formula. I am assuming then that the CPU_OPT and CPU_CHA are PWM only although my manual shows that all OPT_FAN1-3 slots use PWM.

I will be running 6 fans on my front 360 radiator in push/pull, 3 fans on my top 360 radiator and 1 rear exhaust fan.

Is this what you are referring to when you talk about daisy chaining the fan splitters?



Would I then run the far left 4 pin female connector into the CPU_OPT or CPU_CHA header, run the far left molex to the PSU and then connect as many fans as there are fan attachments from the two splitters? Is there a limit?

Ordered my EX 360 D5 Water cooling kit that I said I was going to do months ago. Ah shieee biggrin.gif Gonna need your help guys next week when I try to put this puppy together.

so far as "daisy chain" the PWM splitters... you take one splitter and hook the CPU lead into the CPU or CPU OPT header on the mobo, then you take the second splitter and hook the CPU lead of the that one to one of the FAN leads of the first, so all fan plugs will have PWM information from the mobo. It costs you one fan lead on the first but you gain however many additional leads on the second. You need to hook both splitters up to MOLEX for power. With those splitters all the power is coming directly from the PSU - all you are taking off the mobo is signal. I'd guess you can hook as many up as there is signal strength for. I would guess it would degrade after being divided out too many times but what the limit is, I don't know. (I'd love a device you can plug in one pwm signal and have it maintain signal level to multiple headers.

Yes, I think you will find that all of your chassis fan headers are voltage controlled and not PWM controlled. There are many threads discussing this around. Some of the manuals specify +5v on the 4th wire. Mine specifically says PWM.

I'm not sure what sort of fan speed variation you will notice. I basically only surf the internet and play bf3/bf4 with my rig so when I'm surfing it's super low and quiet and when I play it turns up fast, I don't really notice incremental differences in anything except the main video card's on board fan which does throttle some depending on how quickly I scroll through graphically intense pages as it gets up towards 55c. If the fans are temperature controlled they'll turn down after the temperatures are down, so warm water in the radiators shouldn't be an issue - but liquid cooling PCs isn't my thing. I am an automotive technician by trade (13 years tomorrow!) so I do understand the principals - however I'm sure some of the guys who run under water on here would have additional information to offer.

I am becoming more interested in water cooling since having gone crossfire and the additional air volume and noise associated with keeping the top card at / around 70c but I also enjoy the simplicity of cooling with air and how neat heat pipes & radiators look. Plus my GPUs aren't really worth water at this point as they're dated.

Thank you again for the informative post. Regarding the Splitters, did you see the picture I took of the Gelid splitters? I remade it to offer some specific information. I believe this is what you mean.

yes, that's correct. Technically you should also pull the RPM feedback pin on the second splitter if it has one so you don't have two RPM signals going back to the mobo. Every fan plug will have three wires but the one with the RPM feedback signal will have four wires. (This would be the one you hook up to the actual CPU fan if you had one)

Nice, I should be getting the rest of my gear next week as well, so mutual feeling of stokedness over here. thumb.gif

So, cut the yellow wire on the Splitter plug that connects to the CPU fan header. biggrin.gif Got it.

You have been more help than I could have ever imagined. Now to find out how many fans a single header can handle even using Molex and I should be all set.
