its the driver, somehow the fan spins down as soon you start mining, but the software is its still reporting 100%.
it does happen to all my cards, in both Linux and Windows, except under WinPE.
Topic: 5870 FANS do not want spin at MAX though 100% RPM is FORCED!!! - page 2. (Read 2448 times)
Remove the blue wire on the fan 4pin. No need for software.
This has just happened to another card
One of Gigabyte cards now. Fan spins at ~1500 rpm while max is ~3500.
WTF is happening...
Help please.

Hi!
There is a problem with my HD 5870 V2 and I hope you guys wil help me.
I have 4 cards in a rig 3xGiabyte 5870 and one HD 5870 V2. Generally I run them 3x960\365 and 990\365\1.3v and set those parameters via clocktweak. Everything runs fine BUT then something happens and the fan of HD 5870 V2 suddenly lowers rpm to ~700 though in AB its shown that it is 100%. Clocktweak shows that it is only 15% of its max speed.
Afetr this I can not tweak the card via clocktweak. It says me ERROR: write_values: xxxxxxxxxx whatever I do.
But I can tweak a card via AB for example though fan still spins at ~700 rpm while displayed as 100% in AB.
All the cards are crossfired.
How to overcome this whatever it is?
