Cuttlefish Posted November 26, 2009 Share Posted November 26, 2009 So, a few weeks ago, after downloading a program to monitor my video card's core temperatures, I realized that the stuttering I would commonly get during games, occurred when my graphics core went above 100oC. I replaced the cheap thermal gunk between my cores and the heatsink (which actually flaked off), and it definitely helped, but the core still went above 100oC. Propping my laptop up would make my maximum temperature a few degrees above 90oC, which meant that I no longer stuttered during games. However, while the heatsink and fan were removed, I remarked at how most of its surface appeared to be painted with black paint! What is particularly disturbing is that this heatsink and fan are shared by both the video core, and the main processor of the computer. Indeed, using a program to monitor my processor's temperature, it was not uncommon for it to go above 85oC. Last week, I ordered a replacement heatsink/fan for my laptop model for a little project I had in mind. It arrived this week, and yesterday morning, I began my project of stripping the paint from the heatsink/fan. I gathered my materials: Oven cleaner, 99% Isopropyl Alcohol, and cotton swabs (lots and lots of cotton swabs). Basically I sprayed the oven cleaner into a disposable container (in my case, the bottom of a dismembered bottle of water), and dipped the cotton swabs in it, which I used to apply the oven cleaner to the painted areas of the heatsink. Just like cleaning an oven, you let it sit for a while to loosen what you would like to remove. After a few hours of elbow grease (and cotton swabs), the heatsink/fan was stripped of paint! Here is a picture which shows the old heatsink/fan in the top two panels, and the bottom panels display the replacement heatsink/fan after it was stripped of its paint and stickers and whatnot. I ended up stripping the top of the fan of paint as well, for aesthetic purposes mainly, because, while stripping the paint from the copper heatpipes, the paint from the nearby fan housing flaked off as well. Knowing there was a flakey fan inside of my laptop would have bothered me immensely. So the moment of truth had arrived. I reinstalled the heatsink/fan (having to remove and replace the thermal gunk once again), and I turned on my laptop. Well, it turned on! I loaded my graphics core temperature monitoring program, and I felt disheartened because the idle temperature was the same as before. I dove into my game of choice, and the temperature began to climb, until it hit 76oC, after 45 minutes of gaming or so. The temperature never rose above that point. I also realized that I was not even propping up my laptop, as I had to do to maintain temperatures above 90oC before! Success! So now I ask: Why the hell were the majority of the copper and the aluminum parts of my heatsink/fan painted?! When "Tuxedo Black" was ordered, I really would have been satisfied with the outside of the laptop being tuxedo black. You really don't have to paint the heatsink to keep my attention. The fact that it added around 30oC to my graphics card under load really doesn't help the case of having it look nice either. Maybe it's the geek in me, but I really like being greeted by the chrome surface of my stripped fan when looking into the holes at the bottom of my laptop. I also like seeing the bare aluminum fins peering out of the vent in the back. I know sometimes beauty is chosen over some functionality, but this seems to be taking it to an extreme! As an aside, I think I would rather enjoy a career in building or dissembling laptops! Link to comment Share on other sites More sharing options...
