Overclocking and Excess Heat Production?
 

Does overclocking dramatically increase the heat production of a PC? I bought a couple of Dell PC's a little over a year ago that have quad core 3 GHz processors. I ordered them overclocked to 3.67 GHz (one of the options on the Dell site when I ordered them). Anyway these things produce enough heat to control the climate of a large warehouse in the middle of the arctic.

They're also running a 768 MB GeForce 8800 Ultra Dual. I'm trying to figure out if it's the the overclocked processors or the video cards that are causing the excessive heat output.

Anyone have any ideas?

No big deal, just take them outside and hit with the hose.

I tried that already but it's so hot the water just evaporates the second it hits the PC. :winkwink:

Well then you got me stumped. Good luck.

Yes, pumping excess power through will increase your heat. Bump up your cooling -- make sure you have a case with really good airflow, efficient fans, and air filters to keep the dust out. A nice dust carpet will seal your heat in and not allow things to cool. Also, parts lose efficiency as they age, so they can generate more heat over time. Good luck!

The main heat is coming from the OC cpu's, but I'm sure the GPU's are producing a fair amount of heat as well, along with the Northbridge if Dell had to up the voltage to achieve the 3.67. The 8800's and up tend to have an exhaust port at the bottom of the card that blows down on the mobo and heats it up as well.

I'd suggest grabbing a T.R.U.E. One of, if not the best air coolers you can get.

Not sure if they'll fit in a standard Dell case however. What cases are they in to begin with?
Like Elli said, case airflow is very important. Its one of the reasons I'm rocking this case now - HAF 922

Short answer yes. If you are going to overclock you need to monitor your temps.

Just me but I would never OC any off the shelf computer. If you are going to OC you should build it yourself or buy it from one of the good custom builders online.

Those Dell cases are horrible with airflow. They're so sealed up and usually under-fanned.

Also, what kind of cooler was shipped with the case? Is it just a base Intel fan? I wouldn't trust a Dell overclocked.

listen to this guy.
