Well I got the arctic silver 5 in, applied it and didn't seem like it made much of a difference. Although, I put a napkin on the side fan port and noticed the side fan is kicking on, but only for about 2 to 3 seconds or so, then goes off, and the air coming out is very hot! My laptop is still shutting off, I don't know if i mentioned it or if it makes a difference, but i'm only running on the power supply, no battery. Shouldn't make a difference though, i would think... I have a new 12 cell battery on the way though. This might be a stupid question but, the oily substance i saw when i first took my laptop apart on the heatsink and fans, i was wondering if you know what the R3000 heatsink looks like... if there is some kind of liquid inside the tubes running to the cooling fins? Could it have leaked out if there is fluid in there? I doubt there is but i could be wrong? Could this be where the oil came from and why its still overheating? Or maybe a previous owner spilled something on it, or might have sprayed some WD40 or 3-in-1 oil on the fans if they were rattling... i just read about some people with a rattlin fan problem. Hmm, I dunno what else to do, my fans are coming on, so I guess they are still good?
