Otherwise the fan was clean – apparently my cleaning had payed off at least to some extent. Without any hesitation I removed the thick dust clot blocking air passage from the fan. Lo and behold, temperature readings dropped from 85C on idle to 60C (!)" THIS!!! I found the same exact thing when I was applying new thermal grease to my GTX 285 after I had it running almost 24/7 utilizing Folding@home. It was peaking at 95 C under load! I slowly watched the max load temperature increase throughout the year from a low 65 C up to 95 C. I thought it was the thermal paste so I replaced the manufacture paste with Arctic Silver 5, but then decided to remove the fan top just as you did. I found a thick 'pad' of dust that could NOT be seen without removing the fan. It dropped my peak of 95 C to under 70 C instantaneously. Its been 6 months since I did this and now my max load is slowly increasing, currently peaking at 84 C. I will be cleaning my card every year for this. I thought I had a faulty card, but really it was SUPER dusty! Glad to see someone else discovered this! I'm going to follow your blog. Great minds think alike. “[Dust] was located in the narrow gap between the fan and copper tubing which rendered it invisible from the outside and firmly in place out of reach of my cleaning tools.
