CPU heat sink *never* gets warm -- should I be worried?

[m00g00]

I have a Scythe Mugen 2 attached to an i7 920 (with 1 120mm fan attached) running at 3.36ghz on 1.120 Volts. Idle temps are around 35-39C, under load, 55-58C.

Thing is, the heat sink never gets hot, ever. Not even warm. The only thing that gets even slightly toasty is the "mini heat sink" at the very bottom, but even then I'm not sure if the thing is warm itself or if it just feels warm because of the surrounding chipset and MOSFET heat sinks.

When I put my hand over the top 140mm fan (Antec 300), I always feel cold air blowing out, same with the rear exhaust.

The only thing that seems to exhaust heat is the 5850 video card.

Should I be worried about this? Is my air cooling setup just really good somehow? Or is this normal?

As long as the temps stay where they are and you don't ecounter any stability or slowdown issues your fine.

your body is temp is 37C.

So if your cpu is 35-39C under core temp, its actually spitting out 30ish C air, so yes, it will seem cool compared to your skin temp of 37C.

Load temps 55-58C will spot out warm air. If your saying you cant notice that, then you have a fever and should be in bed sleeping.

If he had a fever that high, he would probably be a pizza warmer....
Or dead.

Get the speed over 4GHz which will require your VCORE to be over 1.3 (unless you have a GOOD chip!) and you will feel heat. If not the CPU will.

That setup looks perfectly normal and you won't feel anything get hot. It's the hot dogs with 4.5GHz setups running 1.5Vcore that are changing the climate.

Okay so everything is functioning properly. Time to OC this thing more, I won't feel comfortable until it is pumping out hot air. I need something to warm my hands besides my aluminum external hard disk.

I was at where you are now. It doesn't seem right that the heatsink isn't hot! I thought I didn't have it mounted right or the stuff in the heat pipes was gone.

At 3.3, the top (furthest away from i7 920 D0) of the TRUE felt cooler than my finger.

At 3.99, with one fan on a clean TRUE, it felt like body temp.

And now with the TRUE needing dusting out, the top feels warm but no where near hot.

CPU-Z shows 1.264V. Real Temp shows upper 70s under load.

I have a e5200 oced to 3.6 ghz at 1.4v (pretty crappy chip out of the lot) with a ac7 freezer pro and it also feels really cool even at max load.

I remember my older cpu heat sinks not being so cool

I notice this happens only with heatpipe sinks. Most solid units do get warm or hot depending on the fan.
