Hopefully an interesting fan question + plea for advice

Hello dear SPCR colleagues!
I turn once again to you for your opinions, help, advice and expertise.
I have been thinking about the following lately:
Let's suppose that we have a Scythe Mugen 3 Rev. B heatsink with the stock fan (SY1225SL12M-P). I think it is generally agreed upon that this can sufficiently cool most/all non-overclocked CPUs.
Now let's say we want to overclock some particular cpu. It is only logical that we would want to compensate for the extra generated heat. Going for a push-pull fan configuration (adding a second fan) with our given Mugen heatsink is one of the options.
Now this is where I got my head tangled up:
The easiest option would be to somehow get my hands on one additional stock Mugen fan, i.e. the SY1225SL12M-P. But these are not sold separately. The only way I can think of to get one would be to buy additional Mugen heatsink and take its stock fan.
Even if I had two SY1225SL12M-P fans, how do I know this is enough? What if I want/need to achieve a better cooling performance (i.e. need to keep the cpu safely cooled while at the same time maintain a reasonable sound level)?
I read on different places (e.g. here and even somewhere on SPCR forums as well) that the gentle typhoon is a better heatsink fan than the Slip Stream. I really don't know if it's true, but let's say that we believe it is and we replace our two stock Mugen fans with two gentle typhoons:
- How do I choose the right model - i mean the RMP rating? How do I know whether, say for example, an overclocked i5-3570k will be sufficiently cooled by two 1150 rpm models? Which leads me to question (*)
As a consequence we loose the PWM ability of the fans that we had before - thus we no longer can regulate the fans with speedfans and/or the fans no longer can be regulated by motherboard. Does PWM makes sense when cooling an overclocked cpu? Don't the tempreatures rise so much that basicaly the PWM would in reality work in the upper range of RPMs anyway?
What about other fans? Which fans do you think would exhibit the best cooling performance (at a reasonable sound level) in a push-pull configuration on the Scythe Mugen?
I am limited a bit by the availability. Out of the recommended fans and the roundup, the Thermalright TY170 is the only one I cannot get.
In a nutshell I am trying to find out whether it's better to try to go for the PWM fans or non-pwm fans, and which ones, when shooting for a dual push-pull configuration for a cpu that we want to overclock.
Another question:
I am looking a for an additional front fan for the define R4 case. There were two fans included. At first I thought that I will just go for a Slip Stream 1200rpm and undervolt it together with the two
included fans using the case fan control. But then I thought that I might look around for a 140mm fan and I ran into these
http://shop.tntrade.cz/vypocetni-techni ... l?scaid=76&
I didn't know these existed. I couldn't find them on the official site. Are these a 140mm versions of slip streams? I also couldn't find any information about these fans nor any review so if anybody has any information could you please tell me?
Could you please give me a recommendation for a 14cm front case fan? I know there are recommendations on the Recommended Fans page, but Noctua is too expensive, the other two were not officially tested, and I don't want the Thermalright - it was designed for a heatsink anyway. Or should I rather stick with the 120mm???
(*)Another question:
Given there is usually a couple of different RPMs available for a given fan model, then generally speaking is it better to get a higher rpm model and then undervolt it or buy a lower rpm model ( a model that is close to the rpm of the undervolted higher rpm model )?
I'd like to thank you in advance for you replies.
Best Regards,
Karol
