Which HSF to choose?
I tested two low profiles fans, only two 23mm tall
HSF available in the USA
in July 2014:
and Akasa AK-CC7129BP01.
I was disappointed when I found that both fans are spinning too fast and making
to much noise in my new chassis when tested with Gigabyte motherboard, so I
test them on ASRock and ASUS motherboards also. I used ASRock FAN-Tastic Tuning and ASUS Fan-Xpert to compare them to stock Intel
HSF supplied with CPU.
Please look at graphs.
As you can see Intel fan can be controlled very well from 981rpm to
3118rpm. Unfortunately it is too big and can NOT be used in our chassis.
Silverstone however (I tested two of them and they are identical) rotates 2269rpm
even with very low fan power = 10% and goes over 3700rpm. It is loud and
not acceptable for our chassis at all. *
The best of these two is Akasa
AK-CC7129BP01, which can be controlled perfectly by
ASRock FAN-Tastic Tuning and
Unfortunately this fan is still too loud on Gigabyte motherboards because
Gigabyte doesn't provide any fan control on Thin Mini ITX motherboards.
So I ordered HSF with fan following different characteristics and this one works
well with Gigabyte motherboards also. Fan is spinning from 598rpm up to 2111rpm according to
FAN-Tastic Tuning and 615÷2265rpm according to
PHT HSF on ASRock
PHT HSF on ASUS
Because ASRock and ASUS have software allowing fan control, both
Akasa AK-CC7129BP01 and new PHT HSF are recommended. For Gigabyte
motherboard only new PHT HSF is recommended.

* I contacted Silverstone USA asking for characteristic modification because
current one does not follow specifications pictured here:
They refuse to make any changes, so I don't recommend
Silverstone NT07-115X in our
chassis. Too loud.
