Scythe Kama Flow 2 92mm Opinions - Page 2

post #11 of 28
Only two scythe I've ever owned burned their bearings trying to push air through an Antec Three Hundred... within a month.

I assume my experience with them is abnormal but you can see which product I'll never touch again.

Gentle Typhoons are Nidec fans. Scythe just gets them from Nidec, puts on plugs and adds some trinkets then sells them to us. GT's are high quality fans.

Also what kind of combined CFM am I looking at with the two Scythe fans because the stock ones have a combined CFM of around 43.

You can't really combine cfm's when you put fans in airflow (not electrical) series. If you have a high cfm pushing and a low cfm pulling, the low cfm will interfere with the output of the high cfm fan. If you put the high cfm fan as pull and the low cfm as push, you may starve the high cfm fan of input air, or at least not add much to your high cfm fan's throughput.

I once had a discussion with Martinm210 about this, and he confirmed that when you put two fans in line you cannot simply add their cfm's to get total throughput.

How do they measure combined CFM then?

Also I am guessing two of these fans will be better than the stock fans Hyper N520 fans.

They measure the output. You can't compute it. For one thing, the resistance of the fin stack will differ between heatsinks. So, to know what your output will be you must measure, and most of us don't have the equipment for that.

I don't really care about the cfm per se, just what the fans actually do. This is why I measure the effects of fans; i. e. - core temps in a standard heatsink setup.

But for a rule of thumb, I figure that if I have a single fan pushing 50cfm, in a single-fan setup the airflow will be less than 50cfm. If I put on a second 50cfm as pull fan, I expect the total output to approach 50cfm. I don't expect more.

So that brings me to my other questions would buying these aftermarket fans be a waste of money then or should I expect to see a noticeable improvement?

EDIT: Because if I would be wasting my money on these fans I may just pick up a H50 instead and save $10, but I really don't know how well the H50 does.

Corsair H50 will obliterate the Hyper n520, no matter what fans you use. Get the H50.

I would really like to get the H50, but I have two worries about getting it.

How long will it last because I really don't want to have to worry about replacing this 1-2 years down the road.

And worried about how it will fit on the back fan with the 200mm side fan on because I heard some people have had problems fitting it on there.
