Hi,

I have just installed a Corsair H80 and used the stock fans that shipped with the unit. The noise from these is very high, sounds like our hoover, is this normal?

I have checked the BIOS and they are running at around 2300 rpm each with the lowest setting selected on the block that sits on the CPU.

I definitely cant work with these but I am not sure if I have a bad pair or if they are normally this loud?

Reading around a bit it seems that quite a few H80 users swap them over for a pair of "Gentle Typhoons", which of the GT's are best for an H80, the 1450rpm or the 1850rpm? If the 1450rpm GT's provide sufficient air flow for the H80 radiator then presumably these would be the quieter option.


Thx for any advice.

I changed the pair of Corsair "stukas" on the H80 for a single Antec Tri-Cool as that was the only spare I had. The difference was astonishing, the Antec Tri-Cool is so much more quiet.

Quite how Corsair get away with bundling these fans with their water cooling kits is beyond me, they are hopeless, way too noisy. At a guess i would think that users just ditch the Corsair fans immediately and use their own aftermarket fans.

Corair "stukas" , absolute rubbish.

I have the 1850rpm gentle typhoons and can say that there aren't quiet at all on 12v however on a fan controller they are amazing. I can hardly hear them and they still shift enough air over a 60mm thick rad.
 
If replacing the Corsair fans with aftermarket fans should I plug the aftermarket fans into the fan connectors in the H80 block that sits on the CPU? Or, should I plug the aftermarket fans into the motherboard or a 12v molex connector from the PSU.

In all honesty, before I removed the stock Corsair fans I am not sure that I had them plugged into the H80 block that sits on the CPU, I think I actually had them plugged directly onto the motherboard.

Possibly they would have been quieter if I had plugged them into the H80 block that sits on the CPU as they would be getting some type of regulated voltage in that situation to control the speed? By plugging the stock Corsair fans directly into the motherboard they would have been running at full speed, hence the "stuka" noise levels?

I changed mine for a pair of noctua nf f12 's.

This vid is me showig a problem i had with the pump on a faulty h80....but in between it makgin an annoying noise you can hear how loud they are at the three settings on the unit.

Theyre now (after the video) set up using a PWM splitter so i control them from the CPU fan header rather than the h80 unit.

I got feed up with this h80 though and have RMA'd it and got a custom loop order in with OCUK instead. Kept the fans, theyre good

...to answer your question, you can plug the aftermarket fans EITHER into the h80 unit or using a PWM splitter to the cpu fan header....either.


The H80 unit has the pump on full all the time. The three settings (low, medium, high) control the fan speed depending on the coolant temp NOT the cpu temp. I found mine to run quieter when plugged into the h80 unit...but I wanted to be safe and put them onto the cpu fan header. I also ran the pump PWM fan cable to another motherboard "chassis fan" header to monitor pump speed. That way if the pump ever failed i'd get a warning as it RPM would drop and be flagged up by man fan controlling software.

Yeah as MrKennedy says, get a pair of 1850 gentle typhoons. The stock fans are terrible. Also if its overly loud make sure the pump isnt working at 4000 rpm, instead of the normal half of that. I had a faulty pump with my first h80 and it was working too hard and the noise was ridiculous. Ive also went to fix 2 other peoples machines, and both had bought a h80 and the same thing had happened. Corsair must be rushing these things out.

I don't plug my gentle typhoons into the h80 box, i stick them into the fan controllers on the board.
