Title: Something amazing happened Post by: Remember remember the 5th of November on January 29, 2012, 11:32:33 PM 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.

Title: Re: Something amazing happened Post by: deepceleron on January 30, 2012, 03:05:37 AM 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.
Title: Re: Something amazing happened Post by: Remember remember the 5th of November on January 30, 2012, 08:16:10 AM 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-RAnd we all know that No fan=heat Title: Re: Something amazing happened Post by: Photon939 on January 30, 2012, 10:10:54 AM 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... ::) Title: Re: Something amazing happened Post by: -ck on January 31, 2012, 12:37:34 PM Maybe because some of us in the bitcoin community still have a sense of humour.

Bitcoin is money. Title: Re: Something amazing happened Post by: Remember remember the 5th of November on February 01, 2012, 11:06:32 AM Well, the "patch" has worn off. It helped, quite a lot. Now it's time for some real oil.
