I have a pro alloy cooler to go on s2 rst and was wondering if it's pos to get a small fan to fix to it keep it cool

 

yes it is possible, how much airflow you're wanting could be the issue as could over cooling.

 

Well the only way to mount mine is to have it on lower cross member under horns if that makes sense cus iv got original spot lights I can't have the cooler where its supposed to b and was guna get a small fan and have it on a switch

 

if you're going to bother with a fan, then i'd get a thermostatically controlled switch fitted and then get a decent small fan, computer ones can be good if you look for cpu ones without heatsinks.

 

Yeah as said computer fans, they're 12V too. You don't need CPU fans though you can get generic case fans with no heat sink

 

You can get some good IP rated waterproof computer fans these days. ive got some of the monster delta fans to be used for additional cooling. Nice high air flow too. And being modern computer fans, they usually all have speed control so you could quite easily set them up at temperature dependant speeds if you have a decent ecu and can make a simple driver circuit.

 

Sounds good I was guna just have it on a switch and turn on when temps are getting high where do I get the waterproof ones from
