Hey all,

I'm having condensation problems. It is oxidizing the back of the motherboard and the CPU socket leads, which then caused the board to short out. Any ideas on how to prevent this? I'm using the seal string and the heater but I am not sure if the heater is working. I just found this problem.

Thanks in advance,

JEWE

The heater should be warm when working.

Mine is 30c so you should feel when it's working.

I don't have any experiences with condensation on the back of the mobo, but my comp is running for 10 hours straight on a LAN without any issues at the moment

This could be from the socket are as well. Sounds like you just have an air leak some place. You can check the heater to see if it works by plugging it into a power supply a it should get warm. I would totaly remount the whole thing. Be careful not to leave any gap arround the heater leads were they come out.

ihave the same problem as well but it's only the back of my motherboard...

i've put sufficient amount of sealstring on the back yet i keep getting water damage... but maybe air is getting in through a gap around the heater leads... hmm..

I live in a pretty dry climate so condensation isn't as big an issue as it is for some, however I've run both with, and without the heater, with no condensation problems. I would agree with what has already been said, check your sealing...

Thanks to all that replied. I will remount it and pay special attention to the seal.

i have had the same problem but i dont have any heater. I used seal string both on the front and the back of the mainboard but the board got so coled that the parts near the memory slott and agp slott got condensation. the sealstring didnt help to prevent condensation. i have athlon 64 and MACH II

The key is to work on the CPU socket. Condensation
passes thru to the back side of the board. Causing
corrosion etc.

Dialectric grease and a square piece cut out of a
mouse pad works pretty good in the center of the
socket. Clear RTV works.

Use some grease like Popcicle said. It will insulate the mobo so the condensation won't affect it.

Yes, this is very true. I also spay the back of the board with several coats of lacquer and use fingernail polish around the socket as well. You could probably throw a bucket of water on my board and it would survive. LOL

what about vaseline. Is it as good as dialectric greas? and silicon...would that work any good? i tough of using silicone and vaseline but im not sure if it works. what do u guys think

I am not sure but I think it can be conductive.

i thought the fingernail polish was just to prevent corrosion...it also prevents condensation?

No it is just for moister protection. It will not stop condensation but it will help to prevent damage from it. I should have been more clear. ;)
