no?
most mine ever got was 50c under full load in a mini itx case with no airflow, it idled around like 30
If you use the stock heatsink it does.
Stock heatsink = 44-46c idle, under load got 54-58c.
If you use a after market heatsink the temps definitely improve, I use a CM Hyper T4 on my pentium rig and it goes as low as 34-36c when under load as high as 42-44c, also it should be noted that the ambient temperature can affect the displayed temps.
I live in california and depending on the weather, if its colder I get way better temps, if its hot the temps tend to be slightly higher, it should be noted that the pentium rig I use is only for emulation (mame, snes, gba, psx) and I never use it for heavy things, also its an older socket lga775 model.
The rig I primarily use has an AMD A8 in it OC'd to 3.9 GHz from its stock 3.6 Ghz, I have tried to go to 4.0Ghz and the highest being 4.2Ghz but those tend to be unstable OCs and I prefer to stay at 3.9 GHz, lowest temps I have gotten on that rig are 28-32c idle and highest are 38-42c, I use a Corsair H50i on it, very quiet.
