About CPU Temperature

[philchen]

HI

I am using the intel core 2 quad Q9450 2.66GHZ
motherboard = evga nforce 780i sli

my cpy temp on real temp
is
temperature
48 41 44 45
distance to TJ MAX
50 58 56 56

Minimum
47 40 43 43

Maxmum
63 55 55 55

Is that hot ? I am using corsair H80 and i installed
for it by myself with no experience. whichi mean first time

when i open battlefield 3 . my cpu load to almost 80% up
and temp is going to 90 C
.it is almost burning .

Help . is that mean i installed the corsair h80 wrong.
the fan is running at 2163 rpm

"edited here: I just saw your temps under cpu load - you neeed to re-seat your heatsink, using an appropriate thermal interface material. I like arctic silver 5, but there are others that are as good."

"and edited here [strike]Those temps are safe. [/strike]" Most like temps 40C or less at idle and ~60C under load.

The ambient temp of the room your system is in will also affect your cpu temperatures, especially if you are air-cooling.

i am actually using the thermal that come with the corsair h80 liquid cooler .
Is that bad? the temp is so strange to very high and drop very fast when idle.
the thermal is that really matter a lot ? i already order a arctic silver 5
but i have no idea for the thermal that comes with.
i didnot installed any fan before . so i might seat the pump not accuratly .

Make sure you have properly seated the H80 water block onto the cpu. There should be enough pressure that you cannot easily move the block on the cpu. Too much pressure can damage the cpu.

OMG. i am so scared. because i make it tight
when i push down .there is no way to move .
and i screw them tightly .but maybe to0 tight.
andway .reseat it and if it is the same .
does that mean my cpu is dead ?

how to do the 100% cpu load on real temp.
do you know that? because it is stay in idle
cpu load on 4.6%

appologize for my english, but hope anyone can help me
without only one person. give me your though.
do you think i need to change the thermal and reseat it
again ?
Is than possible that cpu is still run, but already be damaged?
my cpu running very hot before i install the liquid cool.
and i change my air fan to this . but it still really hot.

It take me whole night to learn and rebuild the pc by myself
but it is so sad. anyone can answer me ?

have you got enough air getting into the case for the rad to work? I hate cheap water, it raises expectations unrealistically.

On cheap air my Q9550 idlesat 35ish and peaks at 55-60.

well you are running so normal .
blowing the air into the case . and take way by the top big fan
. yoour cheap air give you that good
and mine . = = . too bad .

after i taking off the h80 head. . i see some thermal is on the edge of chip. and other parf of top chip is so clean . is that anybody know why ? and the thermal is nothing change at all . it is still a square on the bottom of h80 head.

 

[philchen]

problem has been fixed .but my corsair h80 seams have some noise come out..
i just try it two time until it works .thanks anyone.
i am being dumb .now temp remian constant on 29 C temp even on 60% cpu load
and motherboard are 17 C

Good work! Don't worry about your english, we can usually understand.

It sounds like you applied too much pressure when you first tightened the water block onto the CPU. After you reset the waterblock, you are getting better temperatures. I would leave it alone for now.

If the temperatures start increasing in the next 6 months, consider:
-- getting some new thermal interface material, like Arctic Silver 5
-- removing the waterblock from the CPU,
-- clean the CPU and the waterblock with rubbing alcohol using a coffee filter or other lint-free material,
-- applying the new thermal interface material to the waterblock and to the cpu, and
-- reseat the waterblock (do not overtighten) to the CPU.

None of this is difficult, read the instructions for the thermal interface material you get.
