Fan question in regards to different radiators

[Eddie3dfx]

We all know that certain radiators work better with high-speed fans and others are optimized with low speed fans, so the main question is, are there certain fans that perform well on some radiators but don't work well with others.

For example, would a 38mm fan work better on a thinner radiator, but not perform drastically better than a 25mm fan on a larger radiator.

Do shrouds benefit certain radiators more than others?

I wouldn't think so - however somebody needs to do equivalence testing between push-pull and one high speed fan, I want to know if push/pull can provide more flow with less noise on a GTX rad than one high speed fan can.

depends on how far the fan is mounted from the core @ stock

In almost all cases (basically any restriction more than a basic dust filter), it's more efficient (from a noise point of view) to do push-pull than it is to increase RPM. This really only falls apart at really high RPMs where noise is so high you probably don't care to begin with.

A GTX rad benefits very much from push-pull...fans are nothing more than 'air pumps' with very, very short PQ curves (especially when you consider how much airflow they provide)....doubling the height of the PQ curve is a great way to increase flow.

Let me dig up some old test data I have on a TRUE

EDIT: bah, seems my .xlsx files are all back on my NAS back in Michigan....I have a few graphs on my laptop that are kind of related, but don't show exactly what I'm talking about with noise efficacy of push-pull vs. RPM-increase

Why not you SD You've already done some of the best modding and worklogs possible. Why not poke a little fun at testing.

looking forward to it, thanks for the response vapor, as you have confirmed my suspicions

Honestly, I have seriously considered doing my own radiator fan combo testing, I almost bought all the tools to do it last night - however I canceled those plans because I decided that living in the frat house this year there isnt a chance of me being able to get a consistent ambient noise level. :\
