    Strange Cooling Question

    Okay, here is the situation. I've got a 1.4 AMD Thunderbird that has been running great. Not the greatest performer in the world but still nice. The only problem is that in my (closet sized) dorm room the only place where I can put my case is infront of a nice big sliding glass door. This was no problem during the winter, but as the sun has begun to creep out of the clouds, I've begun to notice my temperature sky-rocketing. When I was running it at home the CPU temp maxed out at less than 50 C. Now at noon on a sunny day it peaks out at 60 C! (As reported by MBM 5.1 and only for a few minutes)

    Does anyone have any ideas about how to rectify this? Should I get a new Heatsink? (right now I'm using the cheap CoolMaster that came with the system) Or does anyone have any other ideas about how to shield the system.

    Thanks.

    How hot is it getting inside the case? If it gets too warm a bigger heatsink on the CPU won't buy you much. You may just need to temperature control your dorm better or if that's not possible, block the case from direct sun exposure. Also, adding additional fans to you case would probably help.

    My case temp is usually around 32 C. I should note that I already have a 3,000 RPM fan mounted in the front grill. Unfortunately, I haven't gotten up the nerve to mod the front of the case so it is still drawing air in through the stock, very small, intakes. I'm just using the powersupply fan for exhaust.

    I would replace the cooler master and add a rear exhaust fan.

    replace the coolermaster, especially the older model ones. also, its never good to have the case in direct contact with sunlight. Though in my opinion, 55-60 is acceptable if not overclocking but not desired

    Change the heatsink, add a case fan for exhaust as stated above, and tape a big piece of cardboard over the glass to stop the sunlight from hitting the case. Or, plain black construction paper will work good. The base would be a white piece of paper with a black piece of paper behind it. The white side should face the sun since white tends to reflect heat and black tends to absorb some.......

    Yes better case cvooling would help. You could also slap a peice of card board in the window to block the sun. You might even add a layer of aluminum foil to the sun side of it. This should help a little.

    Wow! I never expected to have so many responses in such a short period of time! I'll have to post question here more often. Thanks everyone.

    Anyway, I've heard a lot of good ideas about how to fix my heat problem. One that seems to be a common thread is a new exhaust fan. Concerning exhaust fans, I was wondering what the general opinion of slot-based exhauste fans as opposed to other options. I've heard that some are of primary use for cooling specific cards, but do some serve to reduce general case temps?

    or... go to ace hardware pick up some dryer hose vent...very cheap...bolt your existing intake fan you have now in the back by your cpu..under your psu...run the hose vent over your heatsink and fan...make sure your fan is sucking not blowing...flip it if need be..so you have 2 fans sucking air away form your heatsink..you'll have to make sure the dryer vent hose only covers half your heatsink...so it can suck air..route the other end if the dryer hose to your now exaust fan...this should serve you well with very little money spent... gl and post what you do in the end

    Oregon. I suppose it technically is still winter here. But we got a week or so of sun and I diagnosed the problem then. Luckily the sun is less prevalent now, so I have a bit of time to work at it before it becomes a day-to-day event.
