Does Foam Cause More Heat? - Page 2

post #11 of 15
Foam is not heat generating.

Foam can insulate and trap more heat in the case though. However, cases rely on convection to remove the heat from the case (by blowing out the hot air). Very little heat leaves the case via conduction (through the metal case).

As long as you don't block airflow, foam will not affect temperatures that much.

If you put it on the sides, maybe not so much, i mean, its going to make it slightly hotter, but nothing that your going to go "OMG NU!".

But if you put it on the sides, top, bottom, front and back, yeah, expect your computer to turn into a little space heater.

id say go for it, as long as your not covering up any exhaust holes, or anything important like that, you should go for it.

I just installed this foam in my HTPC
http://www.endpcnoise.com/cgi-bin/e/...u=damptek.html
and added two 92mm nexus fans.
I can't vouch for any increase in temps due to adding the insulation, but I can say that adding the insulation and the two fans caused my chipset and video card temps to drop by 10 degrees and the hard drives to drop by about 7 degrees. Also my pc is quieter. Now I just need to replace my PSU fan and it should be near silent. Oddly enough the CPU stayed the same. I thought it was a bad seating, but I redid it and got the same results. Still looking into it.

Just to add, I covered the entire front, both sides and cover of my Silverstone LC17 case, and I only used a little over 1 of the 3 sheets that come in the package above.

Another member put some of this dampening material in his Antec 900. I think it looks great since it's black. I may order some and line the inside of my 900 also. Plus, the stuff is cheap from this site!

After doing a bit of research, I've found that if you buy dampening material labeled as being specifically made for PCs, it's quite expensive. If you can find some good general purpose (home theater, car, etc,) dampening material like the above, you can get it quite a bit cheaper!

I bought this for my CM690's side panel as it rattled a bit more than I could take. With just a sheet of it on the side panel, I can tell you the difference in temps is negligible, but the noise reduction is noticeable.

Ncix also has blocks of the foam, by the same company, to put in empty drive bays. Looks like it would work well in that gap beneath your hard drive cage.

They're a bit expensive, but they do the trick. MNPCtech.com sells some Sonex sheets for cheap - worth checking out, they do international orders through paypal.
