Quick Proc Temperature Question

[ngc4414]

hello:

i building two systems here, both have the same motherboard (MSI 865PE Neo2-V) but different processors: one has a 2.8 GHz E with 1024 cache and 800 FSB and the other is a 2.4 GHz A with 1024 cache and 533 FSB

the faster proc has a temp of about 35 C is the bios, while the slower one has a temp of 58 C in the bios

how come the slower proc has a higher temp? is there something wrong? and for games the proc will probably run much hotter, maybe around 75 C, is that safe?

If those were AMD, they would still be considered in the upper-middle range...

75C is too high.

Other things which can influence heat, besides CPU die size, would be airflow in the case, overheating vid card, disks that run hot (10,000 RPM or SCSI), etc.

What about the presence of a heatshield on the CPUs?

Or even thermal grease?
