n30cortex Posted March 26, 2014 Share Posted March 26, 2014 Hey Guys, my pc fan (CPU FAN) started to turn up to 100% of speed the whole time. >SpeedFan< does not find the Fan any suggestions? (the fan of my GTX is available to set the speed manual) CPU: Intel® Core i7-2600 CPU @ 3.40GHz RAM: 2x 4GB (M378B5273DH0-CH9) Graphic Card: nVIDIA GeForce GTX Titan Monitor: 30" Dell Screen OS: Windows 7 Ultimate x64 Quote Link to comment Share on other sites More sharing options...
excedo Posted March 26, 2014 Share Posted March 26, 2014 (edited) There can be a overload of dust in your PC, try to clean the inside and remove all the dust if it's there, I had the same. But after cleaning my case it was fixed. Also do you use a custom CPU cooler or just the stock one?

n30cortex Posted March 26, 2014 Author Share Posted March 26, 2014 stock cpu cooler. there is no dust in it XD today (before i had to cook) he worked normal. after lunch he just was on 100% the whole time. Quote Link to comment Share on other sites More sharing options...
Antichrist Posted March 26, 2014 Share Posted March 26, 2014 Restart and see if it changes. There could be a background program running, using CPU resources, thus creating heat within the CPU and requiring the fan to run. Quote Link to comment Share on other sites More sharing options...

CruelKind Posted March 26, 2014 Share Posted March 26, 2014 HAHAHA Thunder... @The Problem - Try finding internal fan speed controls that may have come with your mobo. Check the thermal paste compound used on the CPU, perhaps you need to wipe it off and apply more. Perhaps even test a new fan (not a likely solution but possible) Quote Link to comment Share on other sites More sharing options...
Xernicus Posted March 26, 2014 Share Posted March 26, 2014 Is there a "Thermal" section in your BIOS?100% fan speeds are always lovely. I'd flash your BIOS and maybe take out the CMOS battery, press the power button for 5-10 seconds with it out (and unplugged), then put the battery back in and see if it works.

Jacker Posted March 26, 2014 Share Posted March 26, 2014 100% speed - stock cooler - sounds like... meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeehhhhhhhhhhhhhhhhhhhhhhhhh if you love ur cpu - go get a cooler that actually has a chance to keep it low!

n30cortex Posted March 27, 2014 Author Share Posted March 27, 2014 the fan stays after boot at 100% no game nothing running exept "SpeedFan", Skype & xFire... But the Fan isnt listed in SpeedFan. After several boot it doesn't stop. checked my other cooler. same problem XD gonna buy a 18cm ventilator and place it infront of the pc (open case and just the passiv cooler on the cpu) Quote Link to comment Share on other sites More sharing options...

After several boot it doesn't stop. checked my other cooler. same problem XD That's why I believe it is either a BIOS or motherboard issue (hopefully the former, as that requires no money to fix ). Like I said earlier, flashing your BIOS can be a great place to start. I've had harddrive controllers that I thought were dead start working on me again, I/O errors fixed, etc. Quote Link to comment Share on other sites More sharing options...
n30cortex Posted March 27, 2014 Author Share Posted March 27, 2014 bios flash? no thanks. one time done, not again... i can live with the noise got a little subwoofer now beneath my pc sooo i don't hear it anymore when i'm listening to music Quote Link to comment Share on other sites More sharing options...
Ann!b@l Posted March 27, 2014 Share Posted March 27, 2014 How many of time you let your pc turned on? If not enough then try this: -Power Off (no use). -Power On (want to use it). Let it turned on all the day doesn't further to help your cooling system. 1 Quote Link to comment Share on other sites More sharing options...

After several boot it doesn't stop. checked my other cooler. same problem XD gonna buy a 18cm ventilator and place it infront of the pc (open case and just the passiv cooler on the cpu) For the cost of that fan, or less, you can buy ONLY the CPU fan (Assuming the heatsink is a quality unit, if it's low quality, It should also be replaced), and new thermal paste. If those items don't fix the problem, Then it could be the fan speed controller in BIOS/motherboard, at least that's my guess. Or BIOS settings are doing it. But if your fan is bad, and it dies one day while on your PC, that monstrosity won't cool your CPU enough, and if your BIOS doesn't have thermal protection shutdown, guess who needs to buy a new CPU fan, new CPU, and maybe motherboard? You First thing I would do, is verify fan speed settings for the CPU in BIOS. Especially since you said both coolers are doing the same thing. If you don't know how, you can find guides online, or simply google search a BIOS item, and it will tell you what it does. Obviously you need a second working PC to do that at the same time you're in BIOS. QUESTION: How old is the CPU fan that you are currently using that is showing this problem? You can also check your fan condition by opening your case and spin with fan with your finger (With the computer off, obviously). The fan should spin easily and freely. Some fans will have a smooth spin, others will have stronger magnets, and if you spin the fan slowly, you can watch the blades reach a certain point, then they advance forward themselves. But if your blades don't spin much, your fan has dust inside it, or is worn down and needs to be replaced. If those items fail to correct the problem, It might be time to flash your BIOS. I've done it a few times, as well as updated BIOS, without any problems. Quote Link to comment Share on other sites More sharing options...

Change Fan: done, still 100% Flash Bios: done, still 100% change CPU: net yet. going to buy a asus board wirh dual cpu sockel... Quote Link to comment Share on other sites More sharing options...
Antichrist Posted March 27, 2014 Share Posted March 27, 2014 Flashing BIOS is different from verifying CPU fan settings in BIOS, make sure those are all set to Auto/Quiet and Cool or something like that, and not set on Maximum/Full. Also, can you verify that the CPU fan is plugged into the correct spot on your motherboard? It should be Labeled as CPU FAN, and ensure it isn't plugged into one next to it which would be a similar connection, but for case fans.
