Temp Problems

Ok, I built a new system for Christmas (The first I've built) and it's running abnormally hot. According to BIOS, my CPU is running at 71*C while my Motherboard is at 36*C. When I load the software that came with the motherboard (Asus PC Probe II V1.03.02, I also downloaded a different version that shows up as Asusprob in the system tray), it confirms these temperature ratings, however, I downloaded PC Wizard 2006 the other day, and according to it, it's my CPU that runs at 36*C and my motherboard that runs at 71*C as well as my Graphic card running at 50*C. So now, you may see where I'm confused. My question is, which reading should I trust? Since BIOS says the same as the software, I've been going with that, until I opened my computer and felt the motherboard after the computer had been on for several hours and it was pretty hot, though I've yet to take off the CPU fan and feel it. My other question is, I was planning on getting a new CPU fan anyway (Zalman 9700 LED, or would anyone suggest something different?) since I'm using the stock Intel fan, will this cool down the motherboard as well? My computer also runs extremely loud compared to my other (Dell), I turned up the fan speed of the back case fan and it has gotten even louder, but has lowered the temp by 4 degrees (the one rated at 36*C).

My system is as follows:
Cooler Master Centurion Case
Asus P5NSLI
Core 2 Duo E6300
eVGA nVidia GeForce 7600 GT
2GB Corsair TWINX DDR2-SDRAM PC5300
320GB SATA Seagate Barracuda 7200RPM/16MB Cache
Ultra X2 550-Watt SLI PSU

P.S. The PC Probe that I downloaded (Asusprob) also says that my fans are running at extremely high ratings that some aren't even possible (Power Fan 10.5k, Chassis Fan 28.1k and CPU Fan 8.3k - which PC Wizard says the same for the CPU Fan speed). However, the other version I have, says they're running at 2k RPM on the CPU, 2.1k on Chassis and 1.2k on Power.

The thermal pad on the stock heat sink may be a problem there. Generally the Asus Probe II or even the earlier version provide accruate readings compared to non Asus programs like Everest that can see exaggerated temps at times. If you decide on a good 3rd cpu cooler like the Zalman model mentioned you will also want to know one other thing about temps.

Being this is on a prebuilt system(Dell) and not a custom build where you can easily swap hardwares to a better case where larger fans can be mounted you are in a little bind there. One example right off is what was seen here when a cpu fan quit resulting in seeing a 74C then later 85C cpu temp. When the board+cpu were replaced the board saw 48C idle with the cpu seeing 46C idle while the Artic Silver was first bonding during the first two weeks.

What was the solution? The old case having two 80mm fans was replaced by a new one seeing a 140mm front intake and 120mm rear exhaust. Then two 120ss were added to the side cover. Results=board 31C idle - cpu 33C idle
 
I highly doubt that Intel will give you a thermal pad that results with 71*C CPU temps, that's just not logical. Most likely you just didn't seat the heatsink correctly, as I heard LGA775 heatsinks are really hard to install correctly.

It's possible, I never heard the click on the last one I put in but they are really hard to put on and I don't want to push too hard cause it feels like I'm gonna bend the motherboard too far and snap it in half. Anyone have any tricks on putting them on easier?

A pad can have a defect where it wouldn't adhere fully resulting in high temps or may have let simply go after a period of time. The idea now is either reseat the stock hsf or replace it with a better 3rd party cooler. Either way some Artic Silver 5 or even the new and higher priced Liquid Pro is good thing to have onhand. In all cases the hsf original or new has to seated properly.
