GA-MA78LMT-S2(rev3.4). What is TMPIN2?

[K1W1K1D]

Athlon II X2 260, onboard graphics, 4GB RAM(1333), XP home.

Does anyone now what component TMPIN2 monitors on this board?

Why is it much higher than other readings?

TMPIN2 reads 67C(152F).   TMPIN0 is 30C, TMPIN1 is 27C, Core#0 is 23C, Core#1 is 23C, Harddrive is 32C.

Thanks.

Hi there,
TMPIN2 usually reports the Northbridge Temp and, as you are using on-board graphics this is probably why it is showing a higher temp than the other sensors.

Thank you for your reply.

What would you consider to be the highest safe temperature?

Thanks.

 Well it's pretty subjective a subject.....would you really trust AMD or INTEL to a stated safe working temp where there life blood is selling you another replacement eventually ? ... MTBF or "means time before failure" is a calculated average, but the fact remains the lower the temp, the longer a PCB based component will last ... even a few degrees will extend the life of just about any component.

 One of the gems of the after market cooling industry is it allows you to reduce temperatures of any component you so desire, ... by how much is up to you and how deep your pocket is!

 As far as a hard answer to your question........I think it's a personal answer ...I wouldn't be happy with 67C and would probably be going to the effort to post on a good forum

Hi there,

I can't answer your question as getting hold of such information is like getting blood from a stone. The best advice would be to ask Gigabyte Technical Support.

However, these chips to tend to run on the hot side and there are many instances of users showing 60C at idle and 80+C when under load.

If you are seriously concerned you can try replacing the thermal grease on the chip and make sure the heatsink is sitting properly. You can also try adding a small fan to direct cooler air on to the Northbridge area, which is a simple modification that can help.

Aussie Allan.
If you can't trust a manufacturer to advise on the safe working limits for their product, who can you trust?

"I wouldn't be happy with 67C and would probably be going to the effort to post on a good forum"
What would you be happy with?
If I spent some money and got the temp down to 60C, would you consider that a good result?
If this is not a "good forum" could you please post a link to one?

[K1W1K1D]

Absic.
Here is the reply from Gigabyte's Global Technical Service that I received before coming here, "TMPIN2 is some components of MB which should be stlll in normal range." I have gone back to them for clarification. Could be your "blood out of a stone" rules there as well.

I assume that the Northbridge chip is under the black finned heatsink with the pretty blue Gigabyte label cover mounted just below the CPU. The fins are horizontal. I would expect that they should be vertical to get convection airflow for cooling. The blue cover probably doesn't help either.

I also had a look at the airflow through the computer. There is a single case fan at the rear top, beside the PSU exit fan. There are holes at the front for air entry, but I don't think much air comes in there because there is a large mesh grill on the side beside the case fan. I think most of the air comes in through the side, does an immediate ninety degree left turn and goes straight out the rear, without going anywhere near the motherboard.

I have put a sheet of A4 paper over the side grill. At least a piece of cotton thread tries to get sucked in the front now.

I will have a look at adding a fan as you suggested. I will have to connect it directly to a spare PSU connector as ther is only one fan header on the board.

Cheers.

  Maybe I was being a bit too cryptic for somebody near home,  there is NO better Forum,... I was referring to this site you found and posted on !

  I like just about everyone I know on this site  has no financial gain to be had, just the warm feeling of helping people out and be abused from time to time because my last names not Wikipedia with all the answers for people that can't even Speell SEE PEE EWE sometimes.

 "If you can't trust a manufacturer to advise on the safe working limits for their product, who can you trust?" .... your Australian or New Zealand arntch ya !....... I too living in OZ use to be a trusting soul......before I lived in England!

             Who do you trust !

             Your self and TSHK..........The School Of Hard Knocks!

  I trusted S*ny...........Now all my identity details are out there!......Twice!
  I trusted Mar**l.........Now I'm the proud owner of $900 worth of SATA III 6Gb/s equipment that's sitting in a box because I trusted advertising.
  I trusted a CPU manufacture that 85-90C would be fine........and it was for the first 13 months....Twice until I discovered water cooling!

  Reducing Temp even 2C will have a beneficial result and extend life of that component.....I replaced a bridge chip cooler on a X38 board for a friend with a $16 after-market one and got a drop of 27C ....... changing old, cheap thermal paste, adding a fan to blow on a heat-sink, going to an after market cooler.... all these things and more will help in varying degrees whether too effect a better clock , or just extend the life of your investment.

 Here anther little gem that ABSIC touched on (Adding fan)  All fans have a CFM rating (Cubic Feet Per Minute)  I always try and have twice going in as whats coming out going by the figures (CFM) this will give you good air flow and helps keep dust down to a minimum

 Hope this helps you understand what most of us are trying to do!

I think you probably just misunderstood Aussie Allan's sense of humour and I see he has explained himself toyou. He is right though...this is the best forum on the web!

[K1W1K1D]

Kia ora Aussie Allan.
Sorry, but I still don't get the humour in your post.

I do agree with your comment that reducing electronic component temperatures greatly increases component life. This is why I was concerned at seeing the high temperature of TMPIN2 compared to all the other temperatures. Getting credible information on what TMPIN2 is, and what is its safe operating temperature range, is prooving to be a little difficult. The internet is a good source of speculation and missinformation.

I am currently running the computer with the side vents blocked in an effort to draw air in the front, across the motherboard, and out the rear.
Core temps haven't changed, probably because it has a fan, but all the others have dropped by one or two degrees. Hard drive shows largest drop.
I will investigate forced air input by seeing if it is possible to put a fan at the front, and also see what the options are for replacing the Nothbridge cooler, or adding a ducted fan to it.

And now a Kiwi doing a bit of Aussie baiting. "...your Australian..." should be "you're" which is the contraction of "you are".

[Aussie Allan]

  And Greetings to you too K1W1K1D

  Adding extra fan /CFM into the equation will not disappoint in your set-up....Your DVD temp drop confirms there's very little flow coming in the front end..........to expand on what was said about positive pressure.........when a case runs in the negative pressure zone, every crack, slot, vent or hole, sucks air (and dust) with poor cooling characteristics ... against a positive pressure, a small amount of air is lost through cracks,slots and vent keeping dust OUT!

 Addressing the Nortbridge......going off your original post, A small fan or after-market cooler...... this will give the biggest bang for buck re lowering TEMPIN2.

  I know of rigs that have been setup with fans front and rear blowing into the box and a monstrous great fan in the top expelling hot air....works pretty good too.

 core temp wont change that much with case cooling, If you want that to change you'll have to target that area specifically, moving from the least expensive then up!.... Better thermal paste, ducting, clean cold air directly to the CPU cooler through the side of the case (Mod).....change cooler to a higher BTU rated cooler

  And lastly,  "Your" ... "You Are" ... "You're" ...  are placed in text responses purposely for Australians and New Zealanders to give them the effect that they are communicating with a real human and not the computer generated response system that your talking to now!

 The real answer is I use "Dragon voice software" and like all of them, grammar is it's weakest point, 120+ words per minute with 97% accuracy....Grammar typo's sometimes squeeze through.

  Absic ! me old cobber mate!........Every one knows the sphincter is incapable of producing voice patterns, but many an Englishmen has proven to me you can talk through one 

  And how's the Bulldozer project coming along, .... do we have another Donkey carrot release date  ?  even I'm thinking of trying one out, just to see what the hype is all about !

 Aussie Allan

[absic]

Allen,

The Fusion FX (Bulldozer) processors are being dangled in front of us but sadly not until the end of August early September. Still, I for one am prepared to wait for this and I live in hope that AMD finally get this one right. And, if they have to push the release date back even further to make sure that the thing works properly so be it.

Isn't sphincter speak a bit like Klingon? Or maybe it is a little closer to Esperanto insofar as I believe it to be an International language.   

[Aussie Allan]

 Now there a question........what IS bulldozer going to give us/me over what we have aval right now ?

 And "Esperanto and Kligon".... Sometimes people don't understand the English Language, forcing us to revert to Farts and burps to communicate.
