    Hey guys! I've obtained an old HP Opteron system that's old and needs a good clean out. Thinking of using petrol to soak the heatsink to clean out then allowing to dry before rinsing off with isopropyl spray. Good or bad idea?

    this truly is a moment, joined Dec 12, 2002 1 post.

    let me first congratulate you on that one!

    Ok, so heatsink. I personally just dust them and then will use something like toilet paper (don't laugh until you try it) to clean the base of the HS. If I'm feeling special some isopropyl alcohol - just nothing that can leave a residue.

    Totally off topic... but grease in rangehoods: clothes washing powder. It's magic.

    I am curious why and how you've managed to lurk for 16 years

    Although, I must bow to the master lurker.

    In my experience if there's thermal paste you want to remove then turps/shellite/mineral spirits/white spirits (all more or less the same thing) will usually do the best job of dissolving the carrier. IPA is good too. Just not quite as fast and needs more applications and wiping. Petrol is cheap and should work well if you don't mind the fumes (and you're well away from other humans with smell receptors or sources of ignition). Just be sure to have the MSDS on hand. That stuff is super dangerous. https://www.bp.com/content/dam/bp-c...services/fuels/regular-fuels/MSDS Link 95.pdf

    If there no sticky thermal paste then almost anything will work well. You could remove the fan and run it through the dishwasher or maybe the car wash while your filling up your car with the petrol instead.

    water and a scrub brush is all you need. I just run old heatsinks under the tap and scrub away when old systems come through to be repaired.

    Aluminium doesn't play nicely with the typical detergents used in home dishwashers... they will cause pitting and discolouration. Not really what you want on the smooth contact surface of the heat sink.

    It wasn't intended to be the most serious suggestion but fair point. They are highly caustic but usually contain corrosion inhibitors as well. I tried some home anodizing many moons ago (even posted it here I'm pretty sure) and used NaOH to strip the original anodizing. I suspect a go around once would do little harm.

    Right. Not sure why you would need or want to really use anything more than this. They always come up well for me on the rare occasion I actually clean a hs.

    Thanks for the input guys, in the end I went with water, scrub and then liberal side of isopropyl and it worked a treat :)

    I use Eucalyptus Oil,then a gentle wipe with water damp on a paper towel.
    Wife doesn't like the smell, I love the smell. :)

    Most chemical cleaners act as lubricants or contact cleaner. Use the latter avoid the former as it leaves a residual film which acts as an insulator not a thermal translator.
