Random Spooling of H100i Fans

post #1 of 7
Thread Starter 
Dear All:

New to the forum, apologies if this topic has already covered but I couldn't find it in the search..

I have a H100i cooler with 2 stock fans, firmware 1.05. Sabertooth Z77 3770k OC'd at 4.4Ghz.

My H100i has been functioning brilliantly. However starting a couple of days ago it is now randomly spooling up the fans for 2-3 seconds then returning to normal quiet mode. This could happen 6-7 times in a 3 hour period when the computer is idle.

Please see attached PIC detailing temps at idle.

If this is normal?

Your help would be appreciated.

Maybe try bbuilding a custom curve and slide the ramp up point up higher. I suppose the thermal sensor could be going a little whacky too. You should log h100i temps and core temps, there could be some sporadic process kicking in that you would see without logging.

If all else fails you could bypass the h100i fan controller and run through the motherboard CPU header if it can handle the stock fan load.

Thanks for the help I will give it a go.

The weird thing I have noticed is that when the fans do spool up the increased RPM does not show in link which I find odd.

I am also thinking of replacing the stock fans with Corsair SP120 quiet mode fans, what do you think as the stock fans are very loud?

Cheers

Hi Guys:

I think it may be my SLI 680GTX's spooling up for 2-3 seconds for no reason at idle. Not sure what the issue may be there as I had the side of the case off and the sound is the equivalent of when my cards are really stressed for example in Crysis 3.


Any advice?

Cheers

Those have three pin power, I think your best bet if you want to retain the Corsair fan controller is to pick something 4 pin PWM capable. I was just playing around with the Gentle Typhoon AP-15's on mine and while they are killer fans for noise at 1800RPM, the Corsair fan controller really lacks in being able to reduce speed much. About the minimum speed I could get out of them using the corsair pump/fan controller was just under 1400RPM and max wasn't very good either reduced to about 1750RPM and the PWM noise was causing problems too.

IMO, the H100i fan controller really needs 4 pin PWM fans to work right.
Swiftech Helix PWM fans I can control pretty well from about 720RPM-1830
Titan Kukri PWM fans I can control from about 760-2150RPM

Another fan to consider (haven't tried this myself), but the Gentle Typhoon AP-29 is supposed to have the 4th pin on the circuit board such that you can modify it to get 4pin PWM control. Not sure what sort of RPM it would run at for a minimum, but it maxes out at 3,000RPM and has a very similar great noise response as the slower speed GTs. If you wanted better than H100i stock fan max speed performance and better noise, they might make great H100i fans.

Otherwise, I'd probably opt for any sort of PWM fan. The Helix PWM or Titans or Cougar, Noctua, Akasa, etc. all have similar options.

Arctic Cooling F12s are probably the cheapest option, but a little slower in speed at only 1300RPM.

Or the Helix PWM fans spin up to 1800:

Or the Titan which spins up a littler higher to 2200RPM

I would stick with 4pin options though if you intend to use the pump fan controller to regulate speed through corsair link.

Thanks Martinm210, appreciate the help. Sorry for my late thanks as I have been away on business.

I have checked all my 680GTx's and H100i and I think I have identified the culprit. It seems like my Power supply which is an HX1050. The Fan that is randomly spooling up for no reason, i.e. no load or nor high internal temperatures.. Additionally it is making a lot more idle noise than usual.

I have already swapped out a faulty PSU from Corsair and I hope it isn't the first sign of my PSU 'Giving up the Ghost!' so to speak.

Have you had any experience such as this?

Cheers

I have had one OCZ power supply do some really wierd stuff just before failing. Random blue screens and eventually it would simply start up run for about 10 seconds and then shut down. It also made some interesting electrical buzzing type noises. Haven't quite seen the fan speed up thing, but I suppose it could be. Maybe give it a good blowing of for any dust build up and see.

My Corsair TX650 was the OCZ's replacement and so far been a perfect PSU. I couldn't say enough good about my TX650, it's been an awesome and stable PSU for a while now, but perhaps I got lucky..

Hope it was just a hiccup.thumb.gif
