How much benfit can I get from a GT, should I get one?

post #1 of 3
Thread Starter 
Hello all,
I just measured the efficiency of my loop the other day using the method Martin's lab used, which is to measure the Delta T of air into rad and loop water temperature. I got a Delta of 10C, which is considered an average loop. I am using a CM blade master and a generic CM case fan in pull config. So I am wondering if its worth it for me to replace the generic CM fan with a GT AP-15? How much of a difference would I see? These fans cost a fortune so I hope to get some input.
Thanks guys biggrin.gif

You're pretty unlikely to see enough of an improvement to justify their cost, tbh. You're unlikely to see more than a 1C drop unless the fan you're replacing is excessively garbage. Know any details on it at all, like the rpm or anything? 10C also isn't a terrible delta, tbh... 10C delta should be noticeably better than any air cooler. Cooling capability isn't linear, so in order to shave that down to 5C delta isn't going to take a fair bit more than just swapping one of your two fans (another radiator or a larger radiator, for example), and the end result will only be 5C lower load temps, likely not worth the money.

If the generic is truly awful, go pick up a $4-5 yate loon, either medium- or high-speed. They're not as good as GTs, but for the budget segment it's hard to beat.
