What to use to clean gpu

Don't use compressed air. Most dusters are NOT air, or CO2 or N2, but rather solvents like diflouroethane.

Compressed air will send waters, oils, and other dusts into your PC at high speed. a can of duster is a solvent that will evaporate completely.
 


You never want to use a regular shop vac. The dirt flowing down the plastic inlet tube into the vacuum creates static electricity. This static can cause damage to your computer parts.
 
canned air is clean and dry I use my shop compressor with out issue one has a dual filter on it and pressure regulator ??

as far as alcohol all ways check its water content but still never had to nothing over blowing it out ,ever.

Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water. so put water on your electronics ??

good luck

any vacuums like a shop vac or hover [lol] look at all the static discharged from there motors ??? come on . then you suck something off that you not noticed or cant put back or lost ??? then what ? highly not recommended
 
After removing the GPU (best way to clean it thoroughly)... Use a cosmetic soft-bristle brush to loosen/remove dust, dirt, etc. from surfaces, cooling fins, fan blades (hold while doing this). Use canned spray air to blow away the dust you disturbed with the brush.

NOTE: DO NOT shake the air can while spraying the air and hold it (the can) level to prevent the chemicals from coming out. Hold the GPU fan blades as well, so they do not spin when hitting them with the air.

Inspect the GPU for any areas missed and repeat brush/air cleaning as necessary... Then clean the area on motherboard (if necessary) where GPU sits where dust may have accumulated. Reinstall/seat the GPU and PSU cables.
 


A properly grounded PC should be immune to most static, additionally i have never seen an un-grounded shop vac, nor have I ever seen a conductive attachment... I can't imagine the dust in the hose creating enough of a laminar coating to discharge the static. That said, shop-vacs are certainly not intrinsically safe, but I would wager they pose very little risk to a properly wired PC in a properly wired house.


 


Place the GPU on the accompanying anti-static bag it came in, if you still have it. I've been doing this method for almost 20 years without issue(s).

EDIT: or any non-conductive surface/material will do also
 


The antistatic bag is made of a metallic substance and is often conductive. This is a tried and true method, i have no doubt. But on paper, it is ill advised. The reason the antistatic bag is antistatic is because it is a conductive material. You're better off avoiding conductive materials in general when working with ungrounded computer components.
 
as for alcohol never use rubbing alcohol it contains alkaline that are made for the skin not the computer, always use electronics 99.9% computer alcohol.

As for the shop vac I guess my laughing smiley did not across I apologize for mentioning it now as I understand it was misunderstood as serious when I was trying to be funny.
 
To blow out dust I use one of those hand pump things people use to clean contact lenses and camera lenses. No chemicals and it never runs out. I use acetone(or nail polish remover) to clean off old thermal compound. Then you can use denatured alcohol for general cleaning. The water content is higher in rubbing alcohol, so as long as you make sure to properly dry everything that should work too.
 


Rubbing alcohol is denatured alcohol. Denatured just means it has been poisoned (like rubbing alcohol).

Your best bet is a pure chemical substance, always.

Acetone is by far a better solvent than isopropyl but acetone is an absolutely HARDCORE solvent. Nail polish remover is at MOST 60%, and even that is for professional grade salon stuff. Way, way stronger solvent than you need, and way more water content than you want.

You can buy near pure isopropyl at any department store here in the states, but your local laws may restrict the sale of non-denatured spirits. 99% isopropyl means 1% water, which will also evaporate without a trace.
