For the PCH temperature i think that your CPU cooler not send airflow so around the CPU to the PCH

Test with the stock cooler

Look my old post

this motherboard have a lot of problems...

i have this motherboard with:
I3 550
4 gb kingston 1333
hd 500gb western digital blue
palit GT430
cooler master 550w silent
case is a cooler master Elite 360 witha  good Air flow with 2x12" and 1x8"
tried with both stocked cpu cooler and with a new Thermaltake SlimX3

this is what happen...

Watching blu-ray movie (1080p) sometimes...almost always,
computer freeze and shut down!
After this if i try to turn on the computer again, it freeze again before
i see the desktop....
so i have to wait at last 1 hour to see the computer start again.



If i start the computer i see the CPU temp around 28° and the
motherboard/chipset temp at 35°....

after 5 minutes cpu temp is always the same and the motherboard/chipset
is around 55/57°!!! Absurd!

Absurd is that the computer freeze and shut down without any reason..message...event...
How i know what is the cause?

BHA!!!!!!!

With my other HTPC (with an asus motherboard and almost the same component) never had a
single problem, never.

just to know, someone from gigabyte is around?
thx

There are not many times that Gigabyte  representatives come on these forums apart from runn3R who is the forum administrator and is here most days.

case is a cooler master Elite 360 witha  good Air flow with 2x12" and 1x8"

Can you explain please as it doesn't make sense 

[bbwalker]

case is a cooler master Elite 360 witha  good Air flow with 2x12" and 1x8"

Sorry i mean:
1x12" fan (air in, at the left side of the case, just on the cpu)
1x12" fan (air out, up in the case )
1x8" fan (air in, at the bottom of thecase)

hope its better!


Anyway, looks like there is no solution to this, or i'm wrong?
I read in many forum that a lot of peoples have this "strange" problem..."freeze and shut down",
not to mention about the high temp of the chipset/motherboard...!

Thanks. I understand you better now but I think that your measurements are somewhat off as there is no way you have a couple of 12" fans in your case. It also makes a difference how the fans are configured but your seem to be ok in that respect as you would have a slight positive pressure inside the case which is perfect.

yes, there are 2 x 12" fans.

anyway, do you think  this'll be fixed by gigabyte?
Its ok that my cpu is at 29° C and my motherboard temp at 57/59° C ??
And of course its not normal that it randomly freeze and turn off...


bye!

[bbwalker]

Better su send it to RMA?
or Trash it....??

[Dark Mantis]

When it freezes what is the motherboard temperture then ?

What F5BJR suggests is a common issue when the stock cooler is changed for  a more efficient but differently angled heatsink and fan on the CPU. Have you tried replacing the standard heatsink/fan assembly ?

My chipset is also hot that is normal max is some 100 °C ( i have 54 °C at this time  but that is summer !! )

I have added  a fan for the chipset and also for my 2 * HD5770 because with my Adaptec RAID long card the path of fresh air is not great for the second graphics card  !!

if you have : motherboard temp at 57/59° C

You have a problem with your fan's case or the external temperature is very hot

Yes, same problem!
Thats why i changed with a better one.

This is the first time i have a gigabyte motherboard.
I have 4 pc, 2 for work and 2 htpc, all asus except this one with
gigabyte motherboard.

if you have : motherboard temp at 57/59° C

You have a problem with your fan's case or the external temperature is very hot

Pierre

Do you think so?

Why the "CPU" temp is only 27/29° while the motherboard
temp is at 57/59° C?
Even with the "case Open"?
Thats strange...:!!

If i touch the chipset heatsink is very very very very HOT!


anyway...

could be the motherboard temp at 57/59° C that cause, while watching HD Movie
to freeze and shut down?
I noticed also that if i use windows media  player to see the movie looks like all is ok,
if i use total media theater, that use hardware acceleration, it freeze and shut down,
almost all the time.....

That is your chipset or your motherboard ?

For the chipset that is normal

Pierre

[bbwalker]

when i say "57/59° C" is what i see into the bios under "Current System Temperature"!
like in this pic:
 

(of course this is not my temp!!)

the heatsink i mean (thats really tooooo HOT) is the one on the pic, at the left side near the sata connectors:

[Dark Mantis]

Hi

If you are worried about it I would suggest a bit of customising. Add a dedicated fan to cool the heatsink in perticular. Sometimes this is the best way to tackle it.
