QX9650 temp and fan too fast/noisy

Hugo_Sanchez · 15 Apr 2008 at 21:42

I have ran Core Temp and have temps 42,41,37 and 43(not O/C'd) at idle, is that ok, aswell as that I have a Zalman CNPS9711-NT Fan(only 4 months old), at the moment it is running very fast/full speed whilst playing games(don't know temps at full load), I have even changed the settings to Q-Fan Mode in the BIOS, this has no effect, is there something I can do about that(unless I'm not correctly using Speedfan properly) what would the "worst case scenario" be, buying a new fan, and could someone recommend one, price no problem.

You do know about the little black switch on the cooler, for normal/aircraft taking off settings?

Hugo_Sanchez · 15 Apr 2008 at 21:49

(gulp) No I didn't, will have a look for that then. ta.

Hey dr sarf, If there is a switch I can't see it, and I have ran my fingers around the cooler, will I have to unscrew it to move the switch. btw the post should have read 9700-NT

Stop, my bad.

Thought you had the stock extreme cooler. :S

Can you run Prime95 on your PC and monitor the temps while doing so? (use coretemp)
I'm right in thinking fan speed is stepping up during games?

Hugo_Sanchez · 15 Apr 2008 at 22:20

No probs. But if there's no switch would you rec a new cooler? as above, cost aint a drama.

Hugo_Sanchez · 15 Apr 2008 at 22:24

I've not actually ran prime 95 yet, but will do so and get back asap.

I do actually remember that the cooler got a little noisier, but thats when i thought to post a thread just in case I had done something wrong whilst using Speedfan.

dr. sarf · 15 Apr 2008 at 22:29

What are you actually using speedfan for?

Hugo_Sanchez · 15 Apr 2008 at 22:36

I was using Speedfan to see if I could lower the speed of the cooler as it was too noisy(as previously said), since I couldn't do so within the BIOS, obviously that doesn't work. So I thought I was maybe doing something wrong or that my cooler could be faulty.

dr. sarf · 15 Apr 2008 at 22:39

If the BIOS Q-fan is enabled in the BIOS, see how the fan runs according to what your doing on the PC.
For instance if its a cold start, the fan should run slower, then say you run Prime95 or a demanding game, as temps rise, the fan should speed up. Then slow down again as temps drop.

Speedfan can interfere with this and I would not recommend using it.
Let me know your Prime95 load temps, and disable speedfan for now and see if the fan is self-adjusting.

I will do that tomorrow, cos I gotta go to work, hopefully your advice will help.

Speedfan has been disabled and when I start the computer, for the first few seconds the fan is quiet, but a few seconds later it's at full speed even with Q-Fan on. I have ran Prime95 whilst idle, but 24mins into Small FFT's test, it fails saying FATAL ERROR: Rounding was 0.4997558594, expected less than 0.4 - Hardware failure detected, consult stress.txt file. The temps I got whilst running Prime 95 were averaging between 42-54 i.e 42,44,41,38 - 49,46,54,47 albeit the numbers were constantly changing.

The tems are OK but your system isn't stable.

Whats your full spec and have you overclocked?

Hugo_Sanchez · 16 Apr 2008 at 19:36

Apart from my sig what else do you need to know, and no my rig ain't overclocked.

Except the G/cards as they came O/C'd
