is it ok to soak a phenom 955 BE in 90% Isopropyl alcohol for like 5 minuets?

Soak? Why would you consider giving your CPU a bath in alcohol? No, in my book, that is entered as a bad idea.
Not the worst idea mind you, if you were to have a need to do so. I can't think of any offhand. You would then need to soak it in distilled water for about 10 minutes, followed by rinsing well with a bit of distilled water, followed by soaking about 15 minutes (with agitation) in distilled water. Finally, drying it for about 48 hours or more depending upon you humidity and heat - it can be done.
Still not advising it.

just to do a 360 clean. i might have some thermal paste on pins.

I have heard of using a toothbrush, needle or even a toothpick for doing that - never a bath though

hmmmm thx, i probably wont then. i have another quick question my cpu dosent lie flat on my cpu socket. like if put it into the socket its a little uneven.

like the guy that installed my cpu in the first place use this diamond paste and when i took the cpu off the motherboard. the cpu was stuck to the heatsink which caused my cpu socket to bend. i have an am3 cpu socket. is there anyway i can take the cover off the cpu socket and put it back on just to make sure the cpu socket is on correctly?

Check your socket and your CPU for any remains of thermal compound

I'm sorta confused here... what part of the socket is bent? the part that slides? If that part, you may be able to firmly push it down into place. You might have to remove motherboard to do so

Nope, far too fragile for that - I just broke an old AM2 board I had trying it (just to see if it could be done) - best bet: squeezing it into place with motherboard removed

hmmm, sry about your am2 board even though your never gonna use that again. thanks for the experiment.

Not a problem. That is actually why I keep some old mobos around - that and desoldering/soldering practice

Yep, firmly squeezing it should do the trick - you might be able to push it into place with the motherboard still in but be careful if trying that.

Some alcohol may be caught underneath the metal which could cause your CPU to fry.

All it takes is one short path to connect two points that aren't meant to be connected...

i have the same issue with my fx 8150 then i read an article of amd cpu they said u can use the tooth pick to straight out pin but first use a tooth dip into alchol clean off the paste then rinse in to water after drying u look the cpu then try to straight out cpu pins note i have try this to my fx 8150 and its working fine

Careful not to break the pins by using too much force. If you break a pin, it's bye-bye CPU.

I would use a cotton bud and just wipe with the alcohol gently. If you were going to soak it, make sure it is pretty pure alcohol to reduce residue and leave to thoroughly dry out before reseating it.

I cannot see an issue with liberal use of electronic solvent cleaner - which is mainly Isopropyl alcohol. Just be careful of the pins bending, and don't get it in your eyes and wash off your hands. OH and its very flammable so use common sense.

http://en.wikipedia.org/wiki/Isopropyl_alcohol
read the section on uses/solvent.

Water is bad even good quality distilled water is bad, as even tiny impurities in the water cause problems. Yes water is use in the making of IC's but its is extremely pure. and not something you are likely to have handy. The ceramic packages the IC's come in are porous, so any water used may not fully dry by the time you switch it on.
what happens then is the water heats up making stream and can crack the silicon. This is why when reflowing board and placing BGA type chips the IC is gently warm to extract the water content while is been sat on a shelf.

There's no need to submerge the entire CPU in alcohol just to clean the pins. Place the CPU in a shallow plastic bowl type container pins down and pour alcohol in until the pins are covered. Be sure the surface it's sitting on is flat. You may need to place a weight on the CPU to prevent it from floating. Leave it there long enough to dissolve the paste assuming alcohol will do so. It's possible you might need something else like acetone or MEK. I think a quick rinse with distilled water and blow dry with compressed air would suffice to dry it.

Ceramic? Intel has been using an organic substrate for their chips since the day they switched to flip-chip packaging over 12 years ago. AMD has not used ceramic in a similarly long time either.

Most modern ICs are packaged in plastic or epoxy which are much cheaper and allow much smaller packaging than ceramic.

The slow warm-up in the reflow soldering process plays much more important roles than baking moisture: preventing excessive warping and stresses due to uneven heating and deep pre-heating the whole board and components to reduce the amount of heat that needs to be applied to achieve the full reflow temperature for the 10-30 seconds that it needs to be applied. The moisture bake-off is a convenient side-effect.

OK, after much debate...... I have soaked my FX-8350 in 95% Rubbing Alcohol and dried it with a Blow Drier. It is running and performing outstandingly. Hope this answers your question. Also! Rubbing Alcohol has no conductive properties and as long as it dries will cause no problems with electrical equipment. The reason why I dare say "DRY" is because there is 5% H2O and that could cause a problem. BUT! Like cleaning a Bong, The Alcohol will assist in drying the water so as long as you see no trace of Alcohol, there will be no water. ^^

The alcohol does not "assist" in drying the water. Alcohol will evaporate first leaving water behind and then water will evaporate.

The 5-30% water in pharmaceutical alcohol is distilled water, it has very low electrical conductivity as well - as long as it does not pick up water-soluble conductive contaminants like salt. Same goes for alcohol and alcohol-soluble contaminants.
