I have read here that RTV-silicone is bad, bad, bad...
what should I use instead? I have already coated the board with conformal silicone coating...a few layers of spray... I have a can of "Great Stuff" expanding foam spray, but i'm not sure where I should use this, heh... I have a can of "electrical RTV silicone", but it is RTV, so i'm sure it's the bad stuff with acetic acid, and also I've heard allows water vapor to pass... I also have a tube of "Plumber's Goop"...would this work well? |

now i'm confused...RTV stands for room temperature vulcanizing...is it the acetic acid that makes it room temp vulcanizing?

Yes....I want to know about the Plumbers goop. Can it be used in place of silicon. Also....the conformal silicon spray. Where can you get it and whats the brand name/description I should look for?

Cablepro / Doug,
Read the Chemicals article, it has links to all the sealing goodies you could ever want -- plus the links are to the cheapest prices I've seen on the web!

i wouldnt use this stuff unless you find what disolves it. or build a small box around waterblock and pelt to keep it from going everywhere.. |

Use a peltier controller. Overclock to your hearts content then throttle the peltier back down so its operating at a temp greater than the dew point.
I have mine at 15C. Cheers Memphis

Do you have an online source for the controller you use? Local shops here wouldn't even know what I was talking about if I asked for one. |

Here it is:
http://www.oatleyelectronics.com/kits/k140.html Contrary to what they have written, it is pulse-width modulated at a high enough frequency (have to look for the frequency in the instruction). Thanks to the shit Australian dollar this kit will cost you about $10 (minus postage of course!). I have mine running from 14.4V. The supplied heatsinks are insufficient. I replaced them with a Celeron heatsink and fan for the power transistors. Just bent the transistors into an upright position and mounted the heatsink on its side. Used thermal epoxy for the contact. The fan runs from the mobo. Looks and runs sweet! Cheers Memphis

You can also try latex insulating foam sealants (like the DAPtex). The product is very easy to remove with alcohol. 'Great Stuff' is a polyurethane foam, virtually impossible to remove (unless physical).
