PCIe Slot Temperature too High?

I just got a new Mac Pro and installed temperature monitor to make sure things are healthy. I did realise that my PCIe slots are running at 75 degrees celsius to over 80 degrees celsius, which is pretty concerning. Is that normal? I assume thats where the graphics card is attached to.

My Specs are as listed:
Mac Pro (5,1)
Quad Core Intel Xeon 2.8 GHZ
8GB Memory 4x 2GB
ATI Radeon HD 5770 1024 MB Vram [Slot 1]
Mac Pro RAID Card [Slot 4]
4, 1 TB SATA HDDs [Configure to RAID 0, Striped]

Mac Pro Quad Core Customized Build, Mac OS X (10.6.4)

No component in your rig should be idling at those temperatures. What program are you using to collect this data? PCIe temp measurements aren't very common either. If your 5770 is chillin' around low 40s, and all other components are less than 65 Celsius, I can't imagine where that heat would be coming from.

Did the OP run Apple Hardware Test to determine what the problem could be? I suspect that there is a high sensor reading error on the card, but more so I think with the RAID card it might be causing a lot of heat.. Have the OP run AHT and he can then report the results..

If its not the raid card and nothing else, I suspect a faulty fan somewhere or somewhere near the cpu area.
