Temperature probes

[Disrespective]

Ok, so i went and bought myself a new TBred b 1800+ 1.5V version and a Volcano 11 heatsink.

Of course the first thing i do is put my uni books away and try and see how high i can get it to go, and after a little while and waking up Swifty coz he deserved it, i get to 2087MHz at 1.6V with a load temp of 41 degrees.

Thats where the confusion comes up, if i use the Gigabyte hardware health utility it says its only at about 36 degrees, which surely can't be right, and MBM5 says 41 degrees. Also the V11 is only running on just above low when i get these temps.

I would have though that the Gigabye utility would give the more accurate temps because its and onboard probe. True?

My Board is a GA7VAX rev1.0 so the probe isn't situated right under the core, in fact i have no idea where it is, but it must have one that its reading from...... right?

I did lap the heatsink and then get out the cotton polishing bits for my dremel but surely it wouldnt drop temps that well?

Like right now MBM5 says 35 degrees and Gigabyte says 29 degrees, the same as my case. And thats after playing music for an hour or so and having the vis on.

So yeah, can anyone give me any ideas about the temps, i.e. are they correct, and if so which one is more correct than the other.


Cheers

I have Gigabyte GA-7VA with the same problems running MBM 5.3.0.0. Using this version from the previous (5.2?), it has detected two new temp sensors giving 5 temps, plus and extra one which reads zero. Where all these are physically, I have no idea. One puzzle I had was after a cpu fan mod. The stock was changed to an 80mm fan with an adapter. This was good, droped core temp a few deg. Case temp the same.
Two other temps rose, and one fell, all about 5 deg change!?!!
I also have the same discrepancy with the Gigabyte health status, and sorry, no answer for that either :( The case may come apart this weekend and be examined in minute detail for any signs of onbord temp probe. Will let you know if anything found.
Is the Gigabyte sensor on the mobo, and MBM takes its readings from the chip? That would explain the difference. Weather this is true or not:rolleyes:
Mine runs at 55deg (twice), case at 21, and something else at 45 and 46 and 0deg.
If you find anything out, please lets know.

Can you tell me what on earth you got out the cotton polishing bits for :eek:
Shiney doesn't equal better. Flatter does.

Sorry to be off topic.

The shinier the surface, the flatter the surface (on the microscopic level anyways), think about it, the more grooves there are on the heatsink then the less shiny it will be because the light will be refracted all over the place. Thus i concluded that if i were to polish it, firstly by using 1200 wet and dry and then polishing it i would get the best surface.

I did'nt use the heavy duty polishing bits because they would put minute dents in the base because they would be eating into the surface to polish it. And your point would be true.

I could have used car/bike polish in much the same way, the small abbrasive particles in the polish would have removed the very small abbrasions from the sandpaper, and left me with a shiny surface. And not affected the overall "flatness" on the base.
