Hi,

I'm planning on switching out the stock h60 fan for a gentle typhoon 1850 x 2 push/pull setup. I'm also considering using a Akasa PWM adapter:

Questions:

1) Are the typhoons a lot quieter than the stock fan like-for-like, ie can I expect them to be louder than stock at full rpm? Is PWM control even necessary ?

2) will a PWM adapter work on the GT, as I understand it is actually not PWM compatible?

Thanks
 
You need to use Four pin PWM fans with a PWM splitter, otherwise the fans'll just run at full chat all the time. Some of these sealed water coolers feature fan control so if yours is one of them you might just need a fan splitter of the 3 pin variety. If it doesn't control then you'll need to look at your motherboard headers and if they can control 3 pin fans.

I'm not sure what speed the H60 fans are but the other H series fans are 2000-2500rpm jobbies so expect the GT to be a touch quieter.

i use typhoons on my h100 even though they are 3pin. The fan speed control on the block allows you to change speed. But yes, they are a lot quieter. My god when I first got the h100 the fans were as bad as people said (tbh I didnt believe fans could be that loud) it was on par with say, someone hoovering outside your room..
 
Using the same PWM spiltter with Apaches, now the loudest thing in my system is my PSU/HDDs...

Aren't Typhoons better suited as case fans?
 
GTs have good static pressure and have supposedly a less irritating noise signature, or so I've read.
 
so my GT's arrived,

During LINX, my peak temp on the hottest core has dropped from 62 to 54 degrees c, however in gaming I'm getting a similar temp as before when gaming (I'm assuming as the graphics card is also heating up).

I've noticed that during heavy load, my H60 pump RPM drops slightly. Is this normal? I've never paid attention so not sure if this happened before.

Specs:

550w OCZ bronze power supply
i5-2500k @ 4ghz @ 1.22v
gtx560 non-ti (810mhz stock @ 900mhz)
4gig ram
5 case fans
H60 pump
gz68-ap-d3 motherboard
500gig hd

I can't see my PSU not handling my system as I have hardly any other bits, and the graphics card doesn't pull a huge amount of power from benchmarks I've seen.
 
btw* it's dropping from 4150-4250RPM to 4050-4150 RPM. This only seems to happen under GPU load, i.e when running CPU benchmarks it stays normal. During GPU benchmarks with idle CPU, it drops
