Motherboard at 85 degrees?!?

So I have a Dell Inspiron 530 with these specs:
os: windows xp home edition sp3 32-bit
cpu: intel core2 duo e7200 @ 2.53ghz
gpu: nvidia geforce 8400 gs 512mb @ 567MHz
ram: 2gb ddr2

I recently installed the beta version of iobit's gamebooster, and it says my motherboard is running at 85 degrees! How can that be? It's only idling too. I pulled off the cover and there does seem to be a lot of heat radiating from the north bridge, though i don't think its that much. My pc is as stable as ever and never shuts down unexpectedly, so what's up?
 
Try booting into Safe Mode and compare temps - http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true

I assume you have a Good Anti-Virus installed and the definitions are up-to-date. If this is a recent issue, I read the new app, then uninstall it and best to run System Restore to a time prior to this problem.

As said, it's a good idea to periodically clean all components. The simplest method is to use a compressed air canister and blow out all of the excess dust: CPU HSF, MOBO, Case Fans, Case, clean all of the air filters (may require removal of case from access panel, etc -- see case manual. Once a month (5 minutes) I blow-out, clean the filters and vacuum excess dust from case -- and x3-x4 times a year (15 minutes) a deep cleaning -- and every 2 years clean & replace the TIM on the CPU if > 3C from original build temps. Water loops are drained yearly with pre-mix coolant.

I'm getting THRM at 40C, TMPIN0 at 85C, and TMPIN1 at 34C. From what I gather, TMPIN0 is either the northbridge or the CPU socket. Since the CPU is running a good 40C under that I'm going to assume it's the northbridge like I supposed. What should I do? Could it be a faulty sensor?
 
IF all of the above fails then:

1. Clear CMOS via the Jumper method in most instances, unplug the PSU for 5+ minute, then move the Jumper for 5+ seconds (longer doesn't hurt); see -> http://www.youtube.com/watch?v=rdHH9KrceR0

2. Verify ALL fans are working properly. Also try removing removing the Case's side panel and compare temps.

3. IF Clearing the CMOS and Safe Mode and Removing the side panel are still yielding high temps then often this is either a MOBO problem or >3-4 years old system the PSU. A replacement PSU is a good idea.
 

An invalid temp is typically read as ~±124C; no probe.
