Drying out watercooling loop

Hi all,

So I'm moving country soon and my PC is being shipped via Sea and it will take upto 2 months to arrive at it's destination..

I have to drain the loop as no liquids are allowed and it's probably a good idea anyway..

Now I'm worried about corrosion in the loop after being drained.. Would it be a good idea to use an air duster to try and blow out all the remaining liquid from the rads and blocks?

Cheers!

Could you put it somewhere warm like an airing cupboard, and let evaporation do its thing?

Unfortunately I don't have anything like that in my current apartment and annoyingly I'm only going to be able to drain the loop a couple of days prior to moving I'm not sure if that would be sufficient time to be honest..

Ideally I don't really want to be dismantling anything either as time is not on my side

After washing the loop out you could try rinsing it with 99% isopropyl alcohol. IPA has a lower boiling point than water so it should evaporate faster. Goes without saying...keep the room well ventilated.

IPA is bad for plexi though no?

Ah yes it is. I was thinking more for the radiators...the harder to dry stuff basically. For blocks and reservoirs can open it up and dry it manually
(Also wouldn't put ipa in the pump either lol)

Drain it then attach a vacuum cleaner to one removed tube end, with some tape to seal round it. Sucking the air through will do the same as blowing through it, with probably more flow from a vacuum. Leave it running for an hour or something.

This is my idea as well. Either completely disassemble the loop and dry it that way, or blow air through for a few hours
