Fast processors kinna suck......

Anyone think there will there ever be a top of the line CPU that isen't capeable of heating an entire 2 story town house in a matter of hours?

Left my 2.1ghz T-Bred on before I left for work today on accident, almost had a fuggin heat stroke when I opened the door getting home 😛.

 

[jjyiz28]

if your pc is idle i dont see the problem. i usually leave it on but divx some movies, and when i get back its hot.

Your hard drive creates as much heat as your processor... and your monitor creates a ton more... and your power supply itself creates more heat than your processor. And that's assuming your processor is working at 100% duty constantly... which it rarely does.

You obviously do not run DC projects Jeff 😉

No wonder, AMD's run hot 😛

No I don't

I know you're joking... but AMD's don't have to run hot... spend $20 on a heatsink and $5 on a fan and you'll be set.

That won't alter how much heat the CPU puts out though. The only way to make a CPU run cooler is to undervolt it. Less voltage will mean less power thus less heat dissipated to the environment.

true, mine runs 24/7 for F@H
or maybe it's the hot malaysian climate that i'm used to😛

 

[The_Lurker]

lol... I can relate to what you're saying here, thanks to my computer, (2.1 Ghz T-Bred as well), the ambient temperature upstairs is a full 5 degrees higher than downstairs 😛 lol.. of course i do have a Pali 1700+ XP (default) helping it out... damn nice and toasty up here

Yes I am, but it's funny when they complain about heat when they are prolly still using the stock amd hsf

 

[alius]

Well the newer AMD chips run cooler then then their p4 counterparts, so... 🙂

If the air circulation in your house didn't suck, your room wouldn't be so hot. 😛

Well if you're talking about how much heat the CPU actually puts out, then a P4 is hotter than an Athlon XP. That's a big misconception that I've tried to clear up before in many different threads. P4's create more heat, but they have a larger core, so they can dissipate heat more efficiently, thus making them run cooler than an Athlon XP because an Athlon XP's core is about 2/3's the size of a P4's core.

I suspect it was not really the chip itself causing the hothouse effect, it is much more likely to be the monitor. When I leave the house and leave my boxes running, I always turn off the monitors. Even if they go into power saving mode, they still generate enough heat to make it stuffy when I get back. But when I've turned those power gulping puppies off, it's generally only a degree or two warmer.

But I have a 350Mhz P2 Slot processor for you, if you really want something that runs cooler.......:Q

I doubt you got a pally up to 2.1ghz dumbass 😛......., and there were 4 upstairs windows open in the house.

Anyway......

I have an SLK800 and 7 volt moded 92mm Tornado which keeps the temps in the 30-40c area so the chip itself stays at about 34 to 36c idle, 40 to 42c at full load.

I can run a K6-2 500 24/7 with the same PSU and hard drive setup(one 7,200rpm and 2 5,400rpm drives) and notice hardly any heat AT ALL coming out of the back of the computer, much less notice the heat when opeing the door to my house.

The argument of "well duh, we're talking about HUGE increase of power usage with a top end T-bred/P4" is out the window, it's obviously the problem and the added draw makes even the PSU run a warmer in itself.

No need for argument though, I'm just tired of having to have a noisy space heater of a computer just to run my games nice'n smooth or encode to .avi quickly.

PS: the monitor was off, I always turn that off when I leave the computer(by habbit), even if it's to go to the bathroom.

Who's the dumbass? He didn't say anything about having a 2.1GHz... he said an XP2100+.

You guys are confused about this Heat business....

It doesn't Matter HOW BIG OF A COOLER YOU PUT ON YOUR CPU... It Still dissipates the same amount of Heat! Heat = Wattage... You don't decrease the wattage by putting a better cooler on a CPU... All your doing is getting the heat to transfer from the CPU to the Air at a FASTER RATE...

P4's create more heat, but they have a larger core, so they can dissipate heat more efficiently, thus making them run cooler than an Athlon XP because an Athlon XP's core is about 2/3's the size of a P4's core.

Maybe they run cooler because of this analogy, but they still dissipate more heat. It?s total wattage that determines this.

 

[sinensis]

I have an AMD K6-2 400 Mhz and a AMD Athlon 2400+ in my room on 24/7... this combination works great in the winter 🙂

What's your point? You just restated what I said. P4's create more heat... in your terms... P4's have a higher total wattage.

In a word- "watercooling"

especially evaporative cooling (bongs) will chill things quite nicely. Bongs put the heat from your system back into the air through humidity increases. A good (read:large physical size) radiator can do likewise, although not with the humidity increase. The reason is the large amount of water in the system does a great job of retaining it's relative temperature. It takes a WHOLE lot of heat to move water temps up enough to effectively heat your room. This does not apply as much to smallish closed systems (short runs w/o a reservoir).

And ya thought the MHz increase and quietness were the only benefits... 😉

Show me proof. The heat is still created... where you store it has no effect on how much is created... if you leave the computer on long enough, the water will radiate just as much heat as the heatsink on the processor. The reason it appears otherwise is because it takes such a huge amount of energy to heat water. In other words, it doesn't take much heat energy to raise the temperature of air, but it takes a lot more heat energy to raise the temperature of water. So while it may take 1 hour for the computer to raise the room temp 5 degree C, it might take 1 hour to raise the temperature of the water 5 degree C, and another hour for that heat to dissipate into the air and raise the room temp 5 degree C.

And just where do you think the heat goes? Mars? Seriously folks, I don't care if you have a Vapochill, nothing is going to make your CPU produce less heat than it already does, unless you A. turn down the core voltage, B. lower your CPU speed, or C. turn the computer off. CPU's put out major amounts of heat , and it's not getting any better. I remember my first computer that had a fan on the CPU, and thought, "OMG, isn't this overkill?"

ALSO, while we are on the subject, since it was brought up, the cores of the P4's and t-bred's and bartons are not much different from each other in size. In fact, before AMD went to the t-bred, the core on the P4 was much smaller. Don't confuse the heatspreader on the P4 for the core. The P4 would run cooler if the heatspreader wasn't there, but Intel got sick of people crushing their cores and trying to return them.

Moral of the story: CPU's produce heat , so next time, leave the AC on!

 

[Intelligence3]

I read somewhere (actually, in The Economist) that the Prescotts will produce as much heat as a 120-watt bulb. From an area the size of a postage stamp. Yow!

 

[BD231]

There's no plus in his message, and you dont compare a CPU PR number to actual mhz, which it looks like he's doing. The heat output from my processor is greater than his so he shouldn't be mouthing off about household windows.

I'd like to do water cooling, not sure that's the best course of action as overall heat is the main problem and while it may help some I'm not so sure it would do 200+ dollars worth of magic 😛.

Uhhhh, did you not read what i wrote? Because that sounds to me like just what i was saying.

This part is what I take issue with. True, any energy created has to manifest itself in some form or another and "yes" the room temperature will rise regardless of watercooling or not , but MY PERSONAL experience has been that it doesn't rise by the same degree as air cooling. And that is not over some shortened time period of an hour or two. I don't have accurate equipment for taking temps right now (unless you count my cheesy thermometer from Home Depot), but both my roommate, my neighbor who is here all the time, and most of all me, can tell my office had lower temps when I tried evap cooling. Was the air more humid? Yes, but it was actually more comfortable because here in the SGV the air is always too dry to begin with. The fact that we had a "waterfall" sound was an added bonus. Although it did make us have to use the john more... doh! :disgust:

Physics may say otherwise, but I've got two live bodies and myself that will stand by our experience. I do know that my cousins in Grand Rapids and Ft. Wayne where it's more humid said that evaps made their rooms too muggy. So perhaps you're correct and the theory will translate to real world.. hmmm.. I'll hopefully be able to borrow a digicamera to post pics for my new P4 rig next week(my scanner is toast 🙁, and I'll try and get a decent and fair example up of this to back up my belief. It's possible temps are rising by the same degree as aircooling, but even if that's so, at least where I'm at the humidity increase is is a great (and desirable) tradeoff. Anybody else in here have similar experience? Particularly other Angelenos in the Inland Empire/SGV area? With all our friggin' smog and dry Santa Ana winds, I loved my bong. Now that summers here again, it's time to migrate it to a new system! 😀

I can't vouch for closed systems however. I can only relate what others I know with radiator based systems have told me, so I wouldn't be shocked to hear differently.
