Cleaning the dust out of my computer

[dighn]

I use a vacuum to suck the dirt out instead of blowing it all over the place

Youc an't suck it out of the heat sink. And you do it outside, not in your living room.

Wait, what? That's not true. It is still disapationg the exact same wattage, it is just running hotter ebcause it can not diapate the wattage at a lower tempeature. 80 watts at 50C is the same as 80 watts at 60C.

Anyway, I use an air compressor to clean out my cases. takes about 30 seconds or so. I have to blick the fans from spinning though, as I broke a few as they probably spun > 15k RPM when I was blowing the dust off them. (6 CFM at 130 PSI is probably too much 😛)

I know it sounds nuts but that clogged up heatsink really holds the heat.

My cpu is running right now at 86F when if I hadn't cleaned the cpu would be running at approx 100+F.

I've studied upper-level math, calculus, physics and the like and I am telling you... this room is cooler with a cpu running at 86F versus 100F. Did I mention the 68cfm Delta fan on top of that heatsink? Shouldn't it make sense that a cpu running that much cooler with a fan on top of it with that capacity should make a difference in the room temp?

I can with the help of some toothpicks and q-tips

if it held the heat, the heatsink would heat up indefinitely. the rate of flow of heat out of the cpu and the heat out of your heatsink must be equal when it's in equilibrium state. what happens with the dirty heatsink is that it takes a higher temperature difference to have the same heat flow rate. regardless of the state of the heatsink, the heat output of your entire computer should remain consistent. something else must be causing the room temperature difference.

No it doesn't. Your computer would have to be defying the laws of physics.

Explain to me how less drops of sweat dropping off my nads is defying the laws of physics?

I could go into a long dissertation about why you have no idea about the thermal dynamics inside my computers case and the room it resides in but it's sufficient to say you are clueless.

🙂

The fact is that your CPU produces the same amount of heat regardless of how dusty it is. That heat eventually dissipates from the processor to the room, heating the room. A layer of dust keeping heat from leaving the room might make it take slightly longer for the room to heat up. However, pumping heat out of your case faster is NOT going to make your room cooler.

If anything, a hotter CPU means a cooler room, since you've created the same total amount of heat. If it's all stored in the processor, then it's not floating around the air in your room. Cool, the CPu - heat the air, that's the whole damn point of a heatsink.

Apparently now evadman, dighn, and I are all "clueless", because the OP has "studied upper-level math, calculus, physics and the like". Crazyfool - did you actually pass those classes?

OK, mister know-it-all, I don't know what ever possessed me to think that cooler running components would mean my system ran cooler and the room it occupied would be cooler.

I thought I explained about the 68cfm fan on the cpu. Here's the deal... if it can't actually cool itself off even with that fan on it then it becomes a heat source. The cpu is not getting cooled and is still putting out all that heat.

Remove the "blanket" of filth from the cpu and running the same fan means it's blowing it's 68 cubic feet per minute of fresh air on a processor that is running much cooler.

I shouldn't even have to explain this... but I guess common sense is not that common. :roll:

No, notfred... only you are clueless.

I passed every college course I ever took.

I don't know why this idea is so hard for you to put your head around... here's a fine example... put on mittens and wear them in the sun and then tell me why your hands aren't any warmer than they would normally be because your hands are only capable of producing so much heat. Heck... the mittens are not a heat producer and your hands shouldn't get warm. :roll:

Everyone else in the thread except for you seems to have plenty of it.

You aren't blowing any air on a processor. You're blowing air on a heatsink. The reason your processor is cooler is because your heatsink is cooler. Why is your heatink cooler? Because without all the dust obscuring the airflow over it, the heat is moving much more quickly from the heatsink, to the air in your room, thus heating the room.

The processor produces a fixed amount of heat. A cooler processor therefore means a hotter something else. That would be the air in your room.

So you are saying I am right! 😀

Are you comparing the dust in your case to the mittens? If so, your argument only holds water if your entire room is located in the middle of the dusty pins of your heatsink. Yes, the layer of dust keeps heat from leaving the heatsink, just like the mittens keep heat from leaving your hands. That has very little bearing on the temperature of the room the heatsink or the mittens are located inside. Are you telling me that your friend standing next to you would sudenly feel cooler if you took off your mittens because your hands were no longer a hot spot in the room?

only if this:

implies that your room is hotter than before. I thought less sweat would imply that your room is now cooler than before, but I don't know. If you're actually saying your room is *hotter* than before, ok, I can see that happening.

I don't care to argue past this point. But I would like to say that lowering that cpu temp has lowered the room temp to a very noticable degree.

While I understand your points and theories they directly oppose the empirical data I have compiled for myself.

My room is cooler for a fact. I'm sure once the heatsink gets clogged again that it will warm up the room again. Hopefully, it will be winter and I can use the heat.

Peace

the temperature of the CPU tends to rise due to inefficient cooling of the heatsink. this results in air with a higher temperature being blown out which results in a net increase in the temperature of a closed room. the magnitude of the rise in temperature is debatable.

This might be debatable if the temp in this room didn't drop so severely once I cleaned out that heatsink.

We are talking a room temp drop from ~90F to around ~75 or so. All I cared was that my nuts stopped dripping sweat, lol.

True. It is all the more noticeable when the tower is placed close to oneself.

I always wear mittens when I am using my computar. It makes my computing all fuzzy warm and stuff.

BTW, case with a filter on the front FTW. I clean the filter on mine about once every two months or so. I only have to clean the inside of the case twice yearly that way.

ps
Only on ATOT can a question about how to clean out your PC turn into a heated discussion on the laws of thermodynamics. 😀
