CPU Overheating

[RyanRyan52]

I have a few questions about my cpu overheating

I built a pc today with:
RAIDMAX case w/2 fans and a 450 Watt power supply
INTEL Pentium-D 925 Processor
INTEL DG965hw motherboard
1gig of ram
300gb SATA HD
and a DVD drive

I followed the tutorial and the instructions that came with my parts
I planned on installing linux tonight

i turned it on and went into the bios to check the temperature
I left the room for 15 minutes and when I got back the temperature was 70 degrees C
the maximum temp is 64.3 degrees C
I changed the cpu fan settings, restarted it, and now it stays at about 66 degrees C, going up to 70-72 when it first starts

I left it on for an hour to see if the temp would drop
It made my room extremely hot and it didn't drop

My questions are:

• Could this be harmful to the cpu or decrease the performance?
• I really don't want to underclock, but would it help?
• If so, how would I do that?
• Is there anything I could have done wrong?
• Is there an easy way to fix this?

PS I used the fan/heatsink that came with the processor
PPS I used Arctic Silver 5 Thermal Compound

Thanks in Advance,
Ryan

The LGA775 heatsink isn't easy to install if the motherboard is already mounted in the case. Follow the installation intructions found here.

I got the heatsink in sucessfully and the fans are all running but the cpu is still getting hotter than its supposed to

my questions are:

• Could this be harmful to the cpu or decrease the performance?
• I really don't want to underclock, but would it help?
• If so, how would I do that?
• Is there anything I could have done wrong?
• Is there an easy way to fix this?
  

PS Thanks for the link, it'll make it easier for next time

Why are you using Arctic Silver? The retail processor heatsink has compound already applied. Now that you have disturbed that, you need to redo it.

Remove the motherboard from the case and redo the heatsink carefully. Thoroughly clean both the CPU and heatsink with isopropyl alcohol and apply the AS as per the tutorial on their website. Then install the heatsink properly - in addition to Cricket's link, we have a sticky thread in the Tips and Tricks forum. If all 4 pins are not completely snapped down and locked, you will not get the temps down. Now, to answer your questions:

1. It won't be harmful but it WILL throttle performance when it reaches a threshold.
2. You can't under or overclock with that Intel board.
3. Can't do it.
4. Yes, see above. You may simply have too MUCH compound.
5. See above. Emphasis is in bold, this is not optional.

if you applied your own thermal paste, you may have applied too much. how much did you put? you only need like a BB size or two grains of rice. Too much will increase temps

EDIT: beaten to it

Tonight I'll try again and hopefully I'll be successful this time!

Its still overheating

This is what I did:
I took out the motherboard, processor, and heatsink
I cleaned the processor and the heatsink with isopropyl alcohol
I used about about a pea sized amount of the arctic silver
I followed the instructions on the link and got the heatsink snapped in right
I put the motherboard back in and plugged everything in

When I started it up and went into the bios:
The temperature was about 44 degrees and going up quickly
It reached 72, then the fan went faster and it went down to about 65 degrees
It stayed there for 2 minutes until I shut it off

Does anybody know what I can do to fix this?

Thanks,
Ryan

PS Could it possibly be that the case fans aren't good enough?
PPS The mobo temps are 40-50, Is that high?

See if you can disable CPU fan speed control in the bios and see what the temp does with the fan running full speed all the time.

Some of us have a tendency to think more is better. I noticed you used a "pea" sized amount of AS. A pea is much larger than a BB. Perhaps you still have too much AS applied. Something to consider

[RyanRyan52]

How do I disable CPU fan speed control?
I check through the bios and I didn't see it

Is there anyway I could hook the fan up to the power supply?

Or should I get a better cooling system?

Could it possibly be that the case fans aren't good enough?

The motherboard temps are 40-50, Is that high?



Thanks, Ryan

PS I did use a BB sized but maybe I'll try again with less
