Do dual core processors run hotter than single core?

My Pentium D 820 seems to be running hot and need to know if I should add a cooling fan to it to help a little. SiSoft Sandra says that it is mid 50's degrees Celcius and thinking that is too high, or do you split the temp between both cores which would make it about mid 60's Farenheit each core.

Thanks
 
I'd imagine that two cores on one die would run significantly hotter than just one. You could try a high end air cooler such as a Zalman 9500.

So those temps are ok?

Is that at idle or is that under load? What are you using for a heatsink/fan? If you aren't having any issues - i'd say it's ok. When you say "add a cooling fan" - what exactly do you mean, add a fan to the case?
 
Idle and meant adding hs/fan to processor. I only have a big heatsink on it now.
 
WTF are you talking about split the temps?

800 series CPU's RUN VERY HOT. You have 2 full Prescott cores on one die, they put off nearly twice as much heat as a single processor.

I've seen many people hit 80+C with dual cores under load.
 
is there some ductwork with a fan at the end of it? there's no way you can run a passive intel dual core setup unless you had a heatsink about the size of your bedroom ;)
 
not only hotter but the heat is more concentrated as well. your best bet is to have the largest heatsink possible to help dissipate the heat then get a slow turning big fan 120mm which should help keep the noise down.
 
50C idle does not sound unreasonable based on the reviews I read on newegg (hoping to buy an 820 eventually). I would look into Zalmans large 120mm heatsinks, either that or thermalrgiths XP-120 (they make both an alunimum and copper version). Just remember that mass and torque are important consideration as practically all of the good aftermarket heatsinks exceed intel's max wieght limit for LGA775 (which is 450g)
