Kaze Master 5,25" extreme Hot
I got no answer at the german area, so I'm asking here
I bought a Kaze Master 5,25" to controll my 11 Fans.
I got 9 Fans on my Watercool MoRa2 for liquidcooling and 2 Fans for my Case.
All my Fans are "Scythe SlipStream 1200 (SY1225SL12M)".
One Fan need 0,26A - that are 3,12Watt (0,26A*12V).
I connected 3 Fans per channel 1-3 (9 Fans at all) and 2 Fans on channel 4.
This means max. 9,36Watt (0,26A*12V = 3,12Watt * 3 Fans = 9,36Watt) per Channel.
The product description of that Fan controller confirmed that I have 12Watt max. power PER channel.
So I'm not over the limit of that controller.
If I set the potentiometers for channel 1-3 on 50-60% the temerature of the MOSFETs (the red area at picture) rise up on over 100°C (I detected the temperature with the temp. sensors from Kaze Master) and it starts blinking.
It's definitely to hot to touch, I would burn my fingers.
I'm shure that the MOSFETs getting hotter when I set the potentiometers to 100%.
The MOSFET for the 4th channel is only 75°C Hot and the channel runs on 100%.
Are those temps. normal or is that Fan Controller damaged
And I got a second (new) problem:
Channel 1-3 set to 50%.
Channel 1 and 3 attains about 700rpm.
BUT channel 2 got problems.
One of that 3 Fans per Channel stop to rotate and the other 2 Fans slow down to ~300rpm.
To reach the 700rpm, I have to set the potentiometer to 85%.
If it runs about 15min, the Fans slow down again (about 500rpm).
When I put the potentiometer to 90-95%, the Fans JUMP up to 1050-1100rpm.
What should I do now?
(Sorry for my bad english, I'm form germany )
THX for your help.
