CPU Temps - some explanation please

[nomadicdude]

Case - silverstone sg-01
HS - Fanless xp-90
Processor - AMD 939 3700
MOBO - MSI RS480M2-IL
Graphics - MSI 6600GT
Seasonic 430 with 120mm fan <1/4 inch above the xp-90 (essentially no CPU fan)

I'm getting the following temp through SpeedFan.

Ambient - 33 C
Remote 1 - 53 C (don't know the source)
Remote 2 - 113 C (Yikes!! But don't know source)
Local Temp - 40 C
Remote Temp - 42 C
Harddisk - 36C

Does it make sense?

I worried about the Remote 1 and 2 temp. More so because I don't what they are. Any ideas? One of the readers at HTPCNEWS.COM thought the Local and Remote are PWM temps.

Thanks
