Does z68 run hot ?? (what is feels hot)

I have an asrock z68 extreme4 motherboard. The software tools indicate that at idle the cpu is around 30-35c and the mb is in teh same range (around 35c).

However, if I place my fingers on the V8 heat sink (I believe this covers the z68) it is quite hot. Unfortunately I only have touch to go by here. I do not instantly burn my fingers but I think if i left them there for several minutes they might begin to slowly cook.

It is definitely much hotter than the heat sinks around the cpu area.

I am NOT using a discrete gpu; I am using the z68/cpu as my gpu.
-
Basically I'm trying to decide if I should return the mb for a replacement. I rather not since the components are installed and it woudl be a waste to do so if this were normal.
-
I'm not too sure when warm becomes hot but it woudl not surprise me if it were over 170f or well over 60c (I woudl guess closer to 70 or 80) butt his is strictly a wild guess based off of touch - woudl be nice if software would provide an exact value (not sure if there is a sensor for that chip).
-
the issue is that I only have touch to determine the temp; I can definitely touch it (well the v8 heat sink) but if i left my fingers on top for a minute or two I think they would burn - though very low level burn)
-
If this is normal great; but if not I'd like to return it before the rma expires....
-
I do have a digital thermo that I coudl place on top of the v8 cooler; woudl that work? it is not a very accurate thermometer but still if it reads above 180 should i panic ?

Your chipset shouldn't be that hot and it won't be anyways. It will definitely never be hot enough to cook anything. That is as believable as people saying that Fermi cooks eggs.

Using your fingers as a temperature probe is most probably going to give you some inaccurate readings as the normal human body temperature is 37C and most probably the chipset would be in the range of 40-50C max, hence the slightly warm feeling that your finger gets. A digital thermometer is not going to help either as no human body temp goes as high as 50C.

I think it is well above 50c but below the 100c that intel list as the operating range. Does this chip not drive some of the gpu functions ? Would that not cause it to be a bit warmer than normal?
-
I remember that the nforce4 used to get well above 70c and that was considered normal.

When you say chipset do you mean all the chips or just the z68. I.e, most of the motherboard is very cool even the motif around the cpu. It is just the thing labelled v8 that feels hot.

The IGP is with the CPU and not with the Z68 chipset. IIANM the Z68 chipset will only output via VGA/DVI/HDMI but not the processing which is the processor's job.

It should pretty robust and 50C won't cause much harm to it as I've run a CPU at 100C constant a long time ago due to blocked vents and it is still going strong today after some much needed maintenance.

The Z68 chipset is below the V8 heatsink and although the design of the heatsink is not the best when it comes to thermal dissipation(not having fins etc), it shouldn't cause any problems to the chipset.

Ok. I'll do some more testing. Asrock said that one of their tools will give the temp of the z68 itself so I have to reinstall windows (when I tried it before I did not see the z68 temp just the mb temp). The reason I'm concern is tha this syste is suppose to run 24/7. The problem is that fingers are a lousy way to gauge temp (the other reason for this is I have to decide by this weekend if I'm goign to rma the board; which is a lot easier than trying to get warranty service).

My extremely unscientific approximated guesstimate is about 50-55C. This is probably fine, and certainly not RMA worthy if its working well. If you're worried, you can always ditch that tower heatsink you probably have and install a downward blowing cooler (e.g. Noctua NC-H14).

Or, just grab any old small fan you have, some bubble gum, popsicle sticks, zip-ties and duct tape, and make it blow across the heatsink. I turn most of my Intel stock fans (throw away the heatsink) into special purpose fans for this type of use. They last a very long time and they are very quiet.

You are correct that the ASRock eXtreme Tuner Utility just shows Cpu temp and MB temp, so the MB temp must be what they are referring to.

So if you're already running a clean install of windows , then re-installing isnt gonna do any good since thats all the eXtreme utility reads.
Of course, if its not a clean install of windows, then you probably should re-install since its best to start with a clean slate.

Unfortunately i cannot touch the V8 heat-sink to give some idea of a comparison cuz i have two 6950's in the way.

Now take all this with a grain of salt since im not using onboard video.(not even sure that matters)

Ok, i yanked one of my video cards and booted to the desktop then put my finger on the V8 heat-sink and its warm but not so hot i couldnt keep my finger on it for an extended period of time.

So i got a bright idea.
Im not using all the temp sensors for my AeroCool Touch2000 Fan Controller , so i just took the extra one and slid it under the edge of the V8 heatsink.
So this reading is FAR from accurate!
It will just be at best an estimate of the temp of the heatsink itself!
Then i put my other 6950 back in and booted to the desktop.

Just sitting at the desktop the "estimated" temp of my V8 heatsink is 37c

Ok thanks. I think maybe my defn of hot might have been too sensitive. I can leave my fingers on it for 20 seconds without a noticable burn. Also this digital outdoor thermometer -i rested the sensor on top of the heatsink (not sure how you got it under) and it shows around 38 peak (the hw monitor showed 40 peak). So maybe it is fine. I have to say i'm surprise how arm 40 degrees feel. It doesn't cause my skin to blister but it is not a warm fuzzy feeling; more like a hot yucky feeling. I still think it is warmer than 40 but probalby well within spec.

Surprise how well linux runs so far; was worried it would have problems with the new hardward. The only thing I found so far that does not work is resume from suspension.

(not sure how you got it under)
Think of my temp sensors as just a wire with a flat end so they slip under pretty easily.
I'm sure you've seen those before.

Yeah, i dont think there is anything wrong with yours, so its good to hear you're keeping it.

As far as resume from sleep, i dont use it but it is supposedly fixed with the latest UEFI. (i'm running v1.5)
Here is some more info.
edit: LOL, just noticed you are anewbie over there, so ignore that. :biggrin:

I have the same board but I'm not at home so can't poke mine (plus I have no digital thermometer and my hands get icy so they'd be a terrible measure) but just going off it's MB reported temps mine sits around 28c-30c case is nicely ventilated and there's a dualfan cpu cooler installed so the two fans on that will be blowing a lot of air over the MB heatsinks and the ambient temp of my house atm would be between 8c (night) to 18c (midday) give or take a few degrees...if that helps with some more data

Yea. I'm running 1.5 but it might be a linux issue. Anyways i haven't decided if I want the system to actually suspend as it can't perform mail sync in that state so right now I'm not too concern. I still have to move my raid array from the old sys to this one but so far I'm happy with the build. Crude numbers put it at 10x faster than the old one and that's without overclocking.
