I'm planning to attach a secondary fan to my heatsink and as i try to look for the best fan that i will be putting, it seems that i can't really find a secondary fan identical to the primary fan (in terms of speed, etc.) i bought along with the cooler. The only available fan on our area seems to be slower..
My question is.. is it just ok that the pull fan is slower than the push fan? Or what seems to be the proper way of putting it? Does it really have to run at identical speed?
Adding a 2nd fan to my Cooler Master Hyper 212+ only increased the cooling performance by 1c, and that was with a pair of 110cfm fans, so it's really not necessary, if it was a 5c improvement I'd say absolutely go for it but for 1c or possibly less, it's really not worth it.
