Something amazing happened

[Remember remember the 5th of November]

My 5850 was at the brink of death, the fan was buzzing,scratching and basically the sound was horrible.

I opened the card with the intent to remove the fan and re-oil it. Sadly, some screws were stripped, so...I resorted to the hardcore method of forcibly opening it, melting the plastic where the screws were.
So, in the end I was able to open it, making holes in some visible places, but it got the job done. Now, I am well aware of the risks involved in using vegetable oil, either way, I had no choice but to use one
since I had no machine oil and was a Sunday.

Same RPM of the fan, no buzzing, HOWEVER! Temps, were reduced drastically.

Before: 75-81C core, 110VRMs at 600mhz mem,725 core, 1.075mV, 58-60% fan speed.
After: 60C core,83C VRMs, 600mhz mem,725 core,1.075 mV, 45% fan speed.

So basically, temps were reduced with me just re-oiling the fan which just fixed the horrible buzzing sound. It is extremely odd that the temps are now much lower than before.
Of course, since new furniture was purchased, I had to move the computer in a different position, which might have helped about this.

What is the make of the 5850? i have some gigabyte ones with fan issues.

The gzz gzz gzz sound of a dying fan is it spinning up, and then hitting some resonance frequency where it oscillates, causes a whole bunch of friction, and slows down. It is no wonder that the card is cool with a properly operating fan.

Well it's just that the temps are 20C lower. I am ok with that, as long as it's not a sensor bug.

Yup, Just pretend that your fan is at 0%, Even if it rev's alllllll the way up to 90%, If it's trying to reach 92% and it goes GZZZzz--back down to 0-1-2-3-4-5-60-70-80-92%--GZZZzz 0-1-R
And we all know that No fan=heat

You will want to get that fan cleaned and properly re-oiled with machine oil as vegetable oil will quickly turn rancid and gum up, possibly making the fan performance worse than it was.

Make sure to add some fish oil for it to get some more omega 3 or the omega 6 rich nature of the vegetable oil will give it heart disease, cancer and all sorts of other awful diseases...

Maybe because some of us in the bitcoin community still have a sense of humour.

No man.  This is serious.  Bitcoin is money.

Well, the "patch" has worn off. It helped, quite a lot. Now it's time for some real oil.
