Noisy computer is giving me a headache!

Go to solution Solved by blackadder,

Well i would like to be able to controll the fans. so that i can turn them off or run them at low rpm while im doing homework or just want it to be quiet, and then be able to ramp up the speeds if im gaming or doing any other hard work. Are there any other software that will let me controll the fans, or do i need to invest in a fan controller?

other than speedfan, not really. I would reinstall ai suite and set the fan curve to the lowest rpm they spin. Till you do something intensive.

Hi! I have been asking on multiple forums now, but i dont seem to get any good answers or people just have no idea whats wrong... I hope i can find an answer here  :wacko:

 

Ever since i uninstalled Asus Aisuite 2 from my computer (reason being that i just didnt have the amount of controll over my fans as i wanted, and that people really say it shouldnt be used for overclocking) My fans have sped up significantly, they stay at about 80% speed(guessing, as they are very noisy atm...) all the time! it does fluctuate a bit but mosten for the worse, and i dont see why, my cpu (a intel core 4820k at stock speed) is running at 25C idle. My gpu (evga gtx 780 overclocked) is running at 40C idle, to 65C under load. My ram (corsair dominator platinum 16gb) is pretty hot, but not too bad.

 

Now i have searched around the web for clues on how to fix my issue, i have read on forums with no luck, and tried multiple fan controlling softwares, just to mention one is fanspeed, with this as with most of the other software i am just not able to controll all my fans, just a few ones. Like fanspeed only lets me controll my one 140mm fan in the back of the computer....

 

Just to list the nessesary computer specs:

Case: Cooler master Haf Stacker 935

Cpu: Intel core i7 4820k (stock)

Gpu: EVGA Gtx 780 sc (overclocked)

Ram: Corsair dominator platinum 16gb 4x4 kit (at 1333mhz)

Motherboard: Asus p9x79 ws

Liquidcooler: Cooler master nepton 280L

 

My fans are:

1x 140mm in the back(came with case)

1x 90mm in the front (came with case)

2x 140mm cooler master jetflo(came with watercooler and is also mounted on radiator)

2x 120mm cooler master jetflo(bought seperately and placed in front)

Just wire your fans up using the power supply with fan speed reducers in line not that hard

Well unfortunately my pc keeps freezing and crashing with ai suite, displaying error messages as "overclocking failed" and such, it seems it makes my system very unstable...  I still dont think it gives me the full controll id like to have of my fans though, i can set it to increase and decrease fanspeed by the temperature yes, but the lowest i can set my fans in ai suite is 40% which still doesnt turn them off..

The 90mm fan is loud be default. I'd get rid of that and mount 120mm there if it fits. Speedfans problem is that it's mostly meant for PWM fans and has limited support for 3pins. So in all, hardware based controller might be your best shot.

Well the fan mount for the 92mm (in fornt of the haf stacker 915r) only supports 92mm, so i would rather keep it there than throw it away :P

 

I have installed fan xpert only, which seems like its working partly. Now to fully be able to controll the fans myself i do indeed need to invest in a fan controller of some sort as fan xpert only alows a minimum of 40% fanspeed, which still is too much for my taste. 

 

My original issue in this post is now answered i guess, so thanks for all the help!  :D

Am I right in guessing that the radiator is in the small case? 

If so, disconnect that 90mm and put the radiator on the side, pulling air in through it.  (to maintain positive pressure)

 

As for the main part of the case, that has enough airflow to keep your parts cool even with all the fans at half speed.  The difference between half and full speed will probably be 1 or 2°C during normal use and 4 or 5°C under gaming.  Probably even less. 

 

Just for fun : Benchmark it and write down the temps and fan speeds.  Let the PC get back to its normal temperature, unplug one of the front 120mm ones and tape off half of the 140mm at the rear (leaving you with half the normal airflow inside the case).  Then benchmark it again to see how little difference it makes. 

 

Don't worry, it won't overheat.  In fact the CPU and GPU fans should have plenty of RPM left.

Yes the radiator is in the small case, the 90mm fan is in the front in a special bracket made for it, i cant put anything else there so why remove it? XP  :P

 

as or the radiator, it needs to be pushing out air as the screws that hold the radiator in place are so short that i couldnt fit the dust filter in between(unfortuantely...)

 

I have played around with my fan setup today, and i found a setup wich made my pc a lot quieter,(thought i will have to dobule check that i plugged everything in tomorrow becausee i dont have nearly the same noise emission as earlier today  ^_^ )  However i will have to change my setup further, because i think i currently have negative air pressure.   :wacko:

 

I will try benchmarking tomorrow and post results just for funzies  :)
