System fan has failed error after case upgrade.

Specs: Windows 7 Service Pack 1, AMD Phentom II x4 3ghz / 6 gigs
Just a few days ago I moved my HP Pavilion Elite from the standard case into an NZXT Phantom case.
Now, every time I turn my computer on, I get an error stating that the system fan has failed.
I left my old case fan in my old case because I don't need it (I have more than enough case fans, and from what I understand, NZXT fans are the only ones compatible with these cases anyway).
Since the fan from my old case plugged directly into the motherboard, I'm assuming that the reason I'm getting this error is because it no longer detects it.
Can this cause any problems for me and is there any way to prevent this error from showing again?

Do I understand that you don't have the fan plugged in to the m/b? That would certainly explain the error message. I don't think you can supress it, so you'll just have to ignore it.

Update: If you have a look at this link: it may be possible to turn off the system fan check message (look at the bottom of the link).

You either have the system fan plugged into the wrong header or you have or you have a 3-pin plug connected to a 4-pin header.

I'm curious - what do you feel you gained by swapping cases?

@ijack, Yes. I don't have a system fan plugged into the motherboard because all the fans in this case are controlled manually. I'll try that link next time I reset my computer and see if I can navigate through the BIOS to fix it.

@riider, Well, the main reason I upgraded my case was because my old case only had brackets for two HDDs. I've been wanting to install another one, and now I finally have that option.
I was also looking to add USB 3.0 to my front panel, but I didn't have an extra 5.25" bay.
On top of all that; I upgraded my graphics card to an AMD Radeon 6970 a couple months ago, and noticed that the air blowing out of the back of the case was substantially hotter. It wasn't causing overheating problems by any means, but I figured that a pretty case with support for more fans couldn't hurt too much.
