Running 3 fans off one Zalman Fanmate?

post #1 of 5
Thread Starter 
Once my other Gentle Typhoons come in I am planning to run all 3 of them off a single Zalman Fanmate 2.

I've done the math and two GT AZ-00s draw (0.113A*12V)*2=2.71W and the single GT AP-15 draws (0.083A*12V)=0.996W.

That adds up to 3.71W, which is under the Fanmate's 5W recommended max.

The only issue is that the starting currents are 0.53A for the AZ-00 and 0.36A for the AP-15. So, the combined startup power for two AZ-00s and one AP-15 is (.53*12)*2+(.36*12)=17.04W.

So, would it should be safe to run 3 Gentle Typhoons (2xAZ00, 1xAP15) off a single Fanmate 2 with splitters?

I'd say no. The startup current for the AZ-00 is 530mA, which is considerably greater than the operating current. I'd assume the AP-15s would be around 400mA or so. You'd be looking at around 18W to start the fans.

You also need to check the startup specification. During that initial spinning up stage, a fan would require more juice. I do not have those numbers with me but I would think 3 fans (as above) are probably the most you can connect to a Fanmate 2.
