How do you tell what your rpm is for your fans.

Ok I am running speed fan on a evga 760 (x58 I7 960)

Now there are 4 spots to hook up fans on my motherboard. I have all 4 being used. It only shows me rpm for one fan. It s the one that is meant for the cpu. I have a liquid cooling system and it said to make sure the pump is on at least 1500rpm but theres no way to check it.

I should mention that the fan I have hooked up into my cpu slot is a high powered fan. It runs at like 8,000 rpm. I accidently stuck my finger inside the blades it cut them all to hell and it felt like I broke them for about an hour after the accident lol. Luckiley I didnt break my fingers or the fan blades lol. But I'm getting off track. So how do I tell what my RPM"S are


Edit: there are 5 hook up for fans (the bios only shows options for 3)
1. CPU Fan in Bios Shows 8000 RPM
2. Power Fan Not in bios shows no rpms anywere
3. Aux Fan Not in bios shows no rpms anywere
4. System Fan in bios
5. Chassis Fan in bios

I placed all the fans on manual and put all but the numbers to 100 percent but still nothing.

Oh if I place my highpowered fan (4 pin connector) into a 3 pin connection the fan starts and then stops starts then stops. It rotates every 1 sec or so.

1. you plug in your H5O drive pump into the cpu fan header.
The H5O should be a 3 prong connector that looks like a fan header.

The red wire is the + the black wire is the -.. and you have 1 additional wire which is usually blue or yellow. That is called the RPM sense header.

With that 8k rpm fan... my advice.. get a good fan controller.
Here is what i recomend.. something with a rpm display + temp display + has enough amps per channel for you to use WHATEVER fans u may want to use.

Its a bit pricey, but its worth every last dollar:

Shoot I mean the h50 pump goes into a 3 pronged I think one of the accessory inputs. Its the only one it will reach. The fan for the radiator (8000RPM one) Goes into the 4 pronged sorry for the miss communication
