1) Push or pull through a slim radiator (xspc rs360) with low RPM yate loons?

2) Is it OK to use deionised water alone or is it necessary to add anti fungal/corrosive additives?

3) Is there any point in washing out a brand new rad with vinegar or is this process for second hand rads and general cleaning?

1
2 - no and yes (see Galvanic Corrosion at end of first post (link below)
3 (W3bbo cleaning guide towards end of first post)

A polite request to read the sticky and use the search - Watercooling isn't rocket science but you do need to know what your doing to get any benifit over quality air cooling

Just in case you cba to read shadows helpful link:

Push Vs Pull - This depends on fan speed/power. The high speed fans at 2000RPM with a 38mm fan thickness provided the best performance in a push condition. The slow speed fans with 1350RPM with a 25mm fan thickness provided the best performance in a pull condition. I would estimate that performance line is likely to cross in the 1500-1700RPM range where they are equal. So.... slow speed = pull, high speed = push, medium speed = it doesn't really matter.

Oh and also, yes it's worth cleaning out a new radiator just in case there's any manufacturing crap or residue (metal shavings or whatever). Who knows what the quality control departments are like at these places so i''d rather spend a few quid on some vinegar than a lot more if stuff did (unlikely) go wrong.

Anti algae is a must, use PT-Nuke with deionised. Anti corrosion only really necessary if you use mixed metals in your loop, but it shouldn't do any harm either way.

It's no longer necessary to use vinegar as all the new rads use water-soluble flux, so just pumping water through the radiator will clean out anything that's there.

Cheers for the replies guys.

I've read the sitcky, it was very informative and I'm grateful to those who contributed, it just seemed a little outdated with regards to a few things so I thought I'd ask in order to get a more "current" slant on a few things.

I'm not completely new to watercooling either, though previous set-ups have been very bodged or done on a slim budget, this time I intend to do it right.
