Precision T5500 Riser Board Memory Fan Power Connector
MB: CRH6C BIOS: A16 CPU 1&2: Intel Xeon X5650 OS: Win10 64 Pro
I just obtained the 2nd CPU Riser Board. It was a bare board, no CPU, RAM, Heatsink.
Got RAM, CPU, and a heatsink that works with the Intel chipset.
Got a 3rd party adapter to convert the CPU fan from a standard 4-pin connector to Dell's proprietary 5-pin connector.
Problem:
The 4-pin Memory Fan Connector is also proprietary.
It's a different pitch, and smaller pins.
If a 3rd party conversion exists, it's hard to find due to 4-pin fan connectors being so common, getting it to narrow down to Dell's is beyond me.
So, anyone know what the pitch/pin size is?
And is the order of wires the same as with the 5-pin connector?
With that information, I can kludge one up myself.
Currently, I have to F1 past the Memory Fan Error Message at boot, and I'd like to fix that.

Dell is very proprietary, even with their fans. This won't sound like much fun, but the best and safest bet is to use Dell OEM fan(s) and not chance frying aftermarket fan. This also avoids fan error msgs. at startup.
This is not to say aftermarket fan plugged into a Dell MB is absolutely impossible, but it's quite rarer. Only one person in this forum I know was able to make it working by splicing the wires between fan and connector.
