I am about to apply a fresh batch of Arctic Silver 5 to my new CPU/heatsink to replace the stock thermal paste that came with the unit. In preparation for cleaning off the old thermal paste, I followed an Tom's Hardware forum post in which one commentor recommended a cleaning with WD-40 (!) and a paper towel followed by isopropyl alcohol. Because no one corrected this would-be advisor and I didn't know any better, I did as s/he recommended.
Shortly afterward, I went to the Arctic Silver website, whereupon I discovered that one is never, ever to use WD-40 or other petroleum distillate-based cleaners on a heatsink. Horrified, I came here to ask about the extent of the damage I have done. In my defense, I used only a minute amount of WD-40 and immediately wiped down the heating surface with two applications of alcohol.
So, my question: Is this a "my CPU will run a few degrees hotter than it would otherwise" kind of issue, or is it the "buy a new heatsink" variety?
More about :cleaning cpu heat sink prior thermal pasting
Also after cleaning heatsink with isopropyl alcohol (rubbing alcohol has fragrances and higher percentage of water) and heat spreader of cpu
I "tint" (apply small
amount of paste, rub it on heatsink and heat spreader with plastic bag and clean it off with edge of credit card (no metal) so it colors the heatsink and CPU heat spreader)
then I use small line down middle of cpu and then let pressure of heat sink spread paste
By tinting before applying paste the very light covering (coloring) should fill in
microscopic pores in metal therefore achieving a better bond between CPU heat spreader and heatsink
I learned this from this guide from Arctic Silver (there are better pastes but you cant doubt their experience)
here is link: http://www.arcticsilver.com/intel_application_method.ht...
that is for intel there is also on same site application methods for AMD
it is different for different cpu architectures.
Sheesh I am glad I took Keyboarding classes (still can do 60 wpm on a good day)
