Independant 5.25 Temp guage?

[kev5n24]

Hi all,
Long time reader and do to my lack of electrical skills first time poster here.

So I'm looking to fit an externally readable temperature gauge into a computer case. Preferable into one of the 5.25 or 3.5 external bays.

(something that looks about like this)

Here's the thing though, this case isn't going to have a motherboard or normal PC power supply in it. I will however have a 12v power supply wire running into the rig to power some fans.

So basically what I guess I need is one of those temp gauges with it's own temp sensor that can be powered the same way I'm going to power the fans. Ive never used one so I don't know if they usually come with there own sensor or of they get there info from a motherboard.

Can anyone offer me some advice on how to make this happen or maybe point me in the direction of a cheap no frills 3.5 or 5.25 temp gauge that would work in my situation?

Ok so I think I found what I'm looking for but anyone who has actually used a unit like this might know better then me if it will actually require being hooked to a motherboard to function. The way I figure it if I can run case fans off a 12V power supply like pictured above why not a device like this too since it has 4 independent temp sensors? If I'm wrong let me know but I don't think it requires being hooked to the motherboard in anyway. Of course I wouldn't use the sound control part to this unit with no mobo but I might not go with the Kama Meter,.. just using it as an example.

From the looks of the wires it has temperature probes you put on the item you are measuring.

Ya that's what I gather from looking at it too. Which is good and makes me think it doesn't need the mobo but can anyone tell me for sure if this can be powered by a 12V plug pictured above? Again if it works on case fans wont it work on this too?
