Whats Chassis fan, and whys its rpm red?

[KoolAidMan]

My cpu fan is in white with about 4000 rpm but my chasis fan is at 1700 and its in red. Is that a bad thing? Also, why is the power fan 0?

He's talking about the POST screen when you first boot... yes it's fine don't worry your power fan just doesn't have an RPM reader

I'm guessing that you seeing this in something like ASUS probe or in your BIOS screen. Regardless, 1700 RPM is pretty slow for most case fans. If you weren't seeing this before, the fan that is plugged into your motherboard's chassis fan connection may be going bad and need replaced. The power fan connection is usually used for a connection from your power supply that lets your motherboard monitor your power supply's fan. Not all power supplys have such a connector coming from them. Your reading is 0, hence there must be nothing connected to that fan connection on your motherboard.

Feel free to not understand the following. Technically, if you wish, you might be able to hook some other fan to the power connection on the motherboard. This would be useful if you have another fan in the front of the case or top that you would like to monitor. This works as long as the motherboard connection supplies power (i.e., all three connections are provided on the motherboard versus just two connections. Only two are needed to monitor the fan speed. Some motherboard power fan connectors assume the power supply will power the fan inside the power supply and only provide the two connections. If this is the case, you can use a 4-pin molex to 3-pin adapter were the 3-pin connector has only 2 pins used (for speed monitoring). Power comes from the 4-pin molex connector. For larger fans, this adapter is recommended as the fan may draw too much current from the motherboard.
