Can I use 2 x 3 pin fans on a 4 pin Y splitter?

[flamegunners]

Currently, Im using a ASUS B350 Prime Plus Motherboard in a NZXT S340 Elite Case.

The case comes with 2x 3pin fans (one rear, one top), connected via a splitter to a female molex.

Since I will be using the single molex (peripheral) port on my EVGA SuperNova 650W G3 PSU for my led strips, I would like to connect this 2 x 3 pin fans to a 4 pin header on my motherboard instead via a 4 pin splitter ( 1 to 2 ). My question is , is this safe to do so ? Will the power draw be too overkill for my motherboard to handle? Thanks in advance.

No problem. You can run two cases fans off of one mobo case fan header. Most fan headers will supply 1.0A. Case fans generally max out at 0.3 to 0.4A. Thus, 2 fans are fine and 3 fans can be iffy. Also, the 4 pin Y splitter is fine. The 4 pin splitter can be used with your two 3 pin fans. You just don't want to mix a 4 pin fan and a 3 pin fan on the same header.
