New CPU fan problem

Fan problem.

Just bought a new Mobo (Asus H61 M-E) along with a new processor (Intel I5). The Mobo has 2 fan slots, 1 for the CPU and another one for a chassis fan (that is, according to the user manual). The chassis fan that I have is a 3 pin, both slots on the Mobo are 4 headed.
Thing is, the moment I plug in the chassis fan (and starts running at 100% because of the number of pins/slots issue) the main CPU fan stops working. It physically stops spinning. However, when I unplug the chassis fan, everything turns back to normal.

Any idea what to do? Should I get a 4 pin fan?

What is your PSU and full system specs?

Are you plugging and unplugging these while the system is on?

I would turn off the system, unplug the PSU, plug everything in, then plug the PSU in, turn on the PC, and see what happens.

My PSU is a "EXTREME POWER PLUS 600W"
RAM: 8 Gigs.
HDD: 2 separate disk. 320 Gigs and 1 TB.
GPU: Asus GT440
CPU: Intel I5 3340
Mobo: Asus H61 M-E)

There, I don't think I'm missing anything too relevant..

Hmm... May be time for an upgrade soon, but that PSU has good enough power output. Make sure they are all in and that the fan connectors are lined up.

Can you try swapping the plugs for the CPU fan and the chassis fan and see if the same thing keeps happening? Just wanted to see if the motherboard is having a problem supplying the power draw from the fans.

Should I try to plug in the chassis fan while the system is on as others suggested? Never done anything like that.

Nope. Turn it off when you are doing that. I have done it before, but you run the risk of touching some capacitors and burning yourself and possibly causing a short.

Turn it off and maybe switch off the PSU.

Alright, so I switched slots and both of my fans are up and running! I'll still consider getting a 4 pin fan. Not sure how long will I be able to take that fan noise, lol.

Thank you for all your support!

Thank you sir. You're truly a genius on my book :)

Haha thanks. Just make sure that in the AI suite software, your CPU fan (now hooked into the chassis fan slot) has the same fan profile as the CPU fan profile since the chassis fan profile often increases speed / rpm a bit later than the CPU fan.
