Extremely cold temperatures during execution of prime95 (average 55°C)
Extremely cold temperatures during execution of prime95 (average 55°C)
I was quite surprised since I've been using Prime95 for an hour on a quad Q9550 with stock voltage and 1000GHz, and I'm seeing around 55°C, while the Dell T3400's cooler is working fine. Do you think I might have set it up incorrectly? Also, with these temperatures, could I attempt to overclock the Q9550 to 3.5-4GHz without adjusting the cooler? Thanks for your help.
If the t3400 uses the bigger Dell cooler with copper heat pipes, it makes sense. It's a solid cooler built for continuous workstation use. My T3500 ran with an Xeon W3670 that had six cores and twelve threads, and it performed well with the standard cooler. As long as temperatures stay low, you can still overclock it, though I think the t3400 BIOS lacks the necessary features for OC. My T3500 also didn't have that capability.
It looks correct. You might consider adjusting it if you reach 80 degrees Celsius.
It's a 95W CPU paired with a 130W cooler. I've run it at 4GHz using a 130W QX6800 at 1.588V, with the cooler in place. The results are confirmed in my sig. Regarding overclocking, the X38 chipset appears to support 400fsb. You might want to try a 400fsb tape mod—Dell may have allowed that on workstations.
I have my Precision's old Xeon W3670 running on an Asus P6T motherboard, and I'm eager to find out how it will perform. My experience with Intel Core overclocking is minimal, so I'm willing to listen to any advice.

My T3500 ran with an Xeon W3670 (6 cores/12 threads) and performed quite well with the standard cooler. As long as temperatures stay low, you can still overclock it, though I think the T3400 BIOS lacks the necessary features for that. My T3500 did work well after switching to an ASUS P5Q Deluxe motherboard, which is known for good overclocking potential.

My T3500 did work because I upgraded to an ASUS P5Q Deluxe motherboard, which is known for good overclocking potential. It also moved to a retail case, so you're essentially following my approach. However, I chose the cheaper 212 EVO cooler to allow my Xeon to reach 4 GHz, and it performed impressively with a GTX 1060 now.
The T3400 paired with QX9650 is verified to reach 4.15GHz using Throttlestop tools for managing voltage and multiplier settings. The 400FSB won't appear in the BIOS; it will require a tape-based method to set the FSB to 400. This detail is still pending confirmation.
