heat from 4870 is making me sick

[faye]

Just got the Asus EAH4870 for a few days.

Not just talking about the heat it generate is making the case very hot.
It is making my room hot too!

I have been asking how to eliminate (or lower) the heat it produce.
Now what i am using is ATI tool with fan speed for certain temperature and hot key from CCC.

My question now is is there way to eliminate the heat?
I am not just talking about how to exhaust the heat from case to the room.
Is using a heatpipe HSF any better?

the air exhausting from the back of the videocard make the grill too dxmn HOT.

People seem to think that changing a cooler or lowering a GPU temp. change the amount of heat the GPU generates. Think about it, the GPU is making x amount of heat. Changing the cooler may lower the GPU temp, but it's still generating the same amount of heat energy, and that has to go somewhere. If you want to actually lower the heat output you could underclock it and maybe undervolt it? Speeding up the fan will just move more heat from the GPU out the exhaust, this will lower the GPU's temp, but it's still generating the exact same amount of heat energy and sending it somewhere (your room in this case).

Computer rooms are usually warmer than any other room. When I had a CRT it was worst now it's far less heat. I have a fan near my desk for those summer days for hot gaming sessions where it does get hot from sitting on the comp while peaking for a long time. Either tha you can always turn up the AC.

yea slowspyder pretty much nails it, you canjt really lower the amount of heat being produced and puttng on a stronger hsf would probably only makes your room harder by expelling all of that heat into your room. you can try to have some kind of vacuum from inside your case out for window lol ive actually seen that on another forum's extreme mods

I have two highly oc'd quads running seti 24/7 and a 4850 folding 24/7 in my office. unfortunately, my office doubles as the guest room. When both computers are off the room is around 23c, with both on the room jumps up to 26c. this room is very large, however, and has extremely good airflow/ac in it. my old office jumped 6c + with both quads going full blast. In fact, it got so hot that I looked into getting a stand up cooling unit for the room.

theres nothing u can do about the heat in your room except:

vent the heat from the case directly outside of the room
turn off the pc
get better AC

i have put the close to 500/1600 (this is the lowest i can put)

what is the voltage you do? i see it is using 1.263v

 

[taltamir]

open your door, leave it open, turn on ceiling fan...

Also, get a cooler running card, either the GTX260 or the 4850 will do (similar power draw, thus similar heat making).
The GTX260 is about 10 watts more then the 4850, the 4870 50 watts more then the GTX260, and the GTX280 is more then the 4870 (I think it was 40 or so, I don't remember).

The heatsink just changes what temperature the CARD is maintaining, it generates an equal amount of heat regardless of heatsink. (based on power draw).

Since everything blows up at the same time without a heatsink whether it's a GPU or CPU it doesn't really matter how efficient it is or otherwise when it comes to heat. If it really mattered people would hesitate to overclock or buy 3rd party coolers. But you have an option to control heat without compromising the performance (which is far more important to me). There are aftermaket coolers, case blowers, full tower cases, liquid cooling etc - so it's all about proper ventilation and airflow.

get a block of ice to sit in your room. a basic set up of phase cooling.

Create a very low speed profile (200/200 or similar) and use it while idle. Lowering DDR5 speed dramatically decreases card temperature and heat generated.

With all you have to do to get the card form outputing all the heat you should have gotten the 4950 instead. Your pretty much having to limit the performacne of the card to just about match that of the 4850.

LOL, I've actually done this.

 

[faye]

when i change the core and mem clock under profile (using edit),

it doesn't change the actual clock at all. Everest is showing the clock without changing.

Open the window?

yea, i was noticing that... downclocking to 4850 level is a waste. just sell it and buy a 4850 then.

Agreed! Get a 4850 and sell the 4870 if its too much heat. Down grading your 4870 to 4850 speeds is just plain silly. Ceiling fan, more AC , etc.

You might actually like the card more in the Winter months

 

[error8]

Oh, come on, there isn't that much of a difference between those two card in heat output. Maybe the room will be 1 degree cooler with the 4850, but that's nothing noticeable. If it's too hot, just buy an AC unit and enjoy cooler times.

 

[Keysplayr]

You could create some better airflow to your room perhaps? Open a door/window? Put a fan in your window? Fans are cheaper than A/C units both in purchase price and cost to run. There are things you can do without getting rid of your card or even worse, downclocking it. There is no point to that if you spent the money for 4870 performance.

 

[SlowSpyder]

My computer room gets quite hot, not from my PC so much, but because of the way our house is. During the summer I use a window AC unit, it makes things much more comfortable.

 

[Creig]

I suppose you could always just sit in your computer room wearing Speedos...

I thought clocking that low at default volts was a bad idea?

AFAIK, the only way to change voltage right now is hardmodding the card (correct me if I'm wrong, I'm itching to up the volts on my card to see what kind of O/C I can get )

Wait for winter. What were you expecting from a chip with a billion transistors?

If you have a house exhaust fan, running it when the interior temperature is hotter than the exterior temperature can help.
Obviously opening windows / doors in the hot room if it is cooler outside helps.
Try to downclock, put to sleep, or turn off the equipment when you're not using it to keep the initial temperature cooler in the room. Letting in cool air in the evening / overnight / morning helps too.

It is basically too hot here to run much equipment between about 3pm and 7pm but after that it is not so bad. The fall will be here soon which will help.

You can always install a vent or fan like would be used with a clothes dryer, bathroom, or whatever. Some people even enclose their PCs in a box and use a blower / vent to blow that hot air outside.

If you want the ultimate cooling solution, get a water block for the GPU and use either a very large reservoir in the room, or radiate the heat outside with a 2nd cooling loop.
