Hi people, and thanks for all the comments!
MichiganTeddyBear :
I could try to use dehumidifiers ( running at night ) but besides that there is no air conditioning and doors and windows are open all day long... and it's a wide-open area, and there is no option to close that bit down.
I had already tought of using dissecant bags inside the casing, but I was not sure if that would help. I think I'll try it if I can find a big pack for sale somewhere. I don't mind scheduling a "monthly task" for doing this. It would be acceptable.
warezme, JITPublisher :
Thanks for the info on Wd-40 and other oils. As a personnal experience in another similar office, dust usually builds up in an unbelievable way on those PC's, so I'll stay out of WD-40 because of that. Now.. I'll look for those "dry lubricants" , altough I've not a clue of what could that be... is there a know example?
foxyxi :
I'll search for those coatings. I can tape unused slots before applying, and I'll skip fans as I alread expect them to fail after an year... Thanks for reinforcing that tought!
AdamBomb42:
Sorry, Dells are too expensive here in Portugal :-(
celewin:
Thanks for the compliment! And thanks for the tip too! I'll recommend a dehumidifier, but watercooling is not an option: Too expensive ( there are about 10 machines there ) and too much maintenance ( don't watercooling systems need periodic water/liquid cleaning/changing and are prone to misbehave after several months ? Maybe I'm too ceptic about them ...)
I think the problem is both the humidity an the salt (altough salt should absorve water ?). I would rather a simple solution...
sweetpants :
AC or heater it's not a possibility but... I have the habit of using "kitchen extractor" filters in the air intakes of other boxes ( which are in a dusty place ). Do you think these air filters will help ? The problem seems to be humidity filled with salt, I don't think they'll work, but I could try.
cb62fcni :
Thanks for the tip. Do that also applyes to "dry lubricant" as suggested by JITPublisher , and for the "conformal coatings" suggested by foxyxi?
I'll search for those Vapor Corrosion Inhibiters.. the link you pointed has dissecants and coatings... Are you suggesting something special that is on that page and that I missed? Or all of those are VCI?
OOPS! I was not notisting you second post! It's kind of a dissecant, right?
Trakz:
I'll look up the document! thanks! Living near a beach is good during the summer but chilly during the winter... humidity gets inside your bones!
Thanks for all the help people! I hope the things you referred at available here in Portugal, but hey, there is always international shipping, right?
Thanks again!
