Dell XPS M1330 CPU Temperatures.....

Hello, this is just to tell you all something very interesting which I can hardly believe.

I have a T7300 Processor and today after thinking that the fan was coming on too much I changed the thermal compound imbetween the CPU and the heatsink.

It used to be idling on high performance from around 50 degrees to 58 degrees. And on power saver around 46 degrees to 50 degrees

I have now changed the thermal compound to Arctic Silver 5 and guess what......

Power Saver = 32 Degrees to 38 degrees
High Performance = 35 degrees to 40 degrees

!

I thought that it would maybe change the temperature by around 3-5 degrees but it has infact changed them by 10 whole degrees!

I really am quite shocked...........

 

Good for you. I hear it will keep improving as it takes time to cure. You can look it up I believe it is rather long so maybe will even get much better.

 

Thanks for the advice. My temps dropped 11C after letting it sit overnight! Whats even better is that the temps don't gradually climb till the fan comes on.
T7500 and 8600M Idle: cpu 43C gpu 56C

 

How do you access the CPU to change the heatsink compound? Are there instructions somewhere (hopefully with pictures/video)?

 

I wouldn't mind seeing a how-to on this myself; my temps are 117/120 with light surfing on power-saver mode.

 

Make sure battery and A/C adapter are plugged out.Take off the back panel where the RAM is located. Unscrew the heatsink screws. Remove the thermal compound with isopropyl alcohol from both the gpu and cpu. The chipset with the blue thermal pad leave that alone. Apply new thermal compound, only a small amount them spread it evenly/thinly onto the cpu and gpu. Screw everything back up. It will get cooler after you give it some time to settle in.

 

Thanks for the instructions! I'll give it a try when I get home.

 

I did this a week after i got my 1330 and I immediately noticed a marked improvement...

 

Temperatures?

 

Hmm, I didn't change anything on the GPU, where is that? Is that on the same heatsink?

 

Same heatsink. Do you have a dedicated card? It looks like the cpu but says nVidia on top.

 

Yeah, I have the 8400GM but there wasn't any heatsink on it to begin with?

 

How often do your fans come on now?

 

Nice... i'm interesting to give a try but... how to apply the Arctic Silver 5 ? i saw your trips... but the thing is... googling i found some articles telling that i should spread all over the chip, and other just over the core so.. what's the true??

another thing..warranty.. doing that am i loosing it?

cheers beto

 

Two options:
Put a pea side amount onto the metal part of cpu. Then put the the heatsink back on.
Or put the thermal paste on the cpu then smooth it over with a thin layer. Reseat heatsink.
Warranty: Just do a real clean job and no one will know.

 

Thanks ....really helpful

OOOk... it means a good challenge for clumsy people ... i pass thank... ahhaha thanks anyway

 

Is there much change of actually skrewing up the laptop if you put new thermal paste on?

 

Use non conductive thermal compound.

 

What program did you use to monitor the temperature?

Thanks

 

AS5 is much more efficient than the ceramic equivalents. A pea sized amount is HUGE! Use a grain of rice sized amount.

I use RMClock to monitor temps, under volt the CPU and to stop CPU whine.

 

I just did mine with some ceramique AS and have not noticed any difference so far since powering up about 20 minutes ago. On high perf I have 45c roughly on both CPU cores and 66c on the GPU. Just typing this out, nothing else going on.

Also, the blu thermal pads were present on the GPU and I guess a northbridge chip, the only chip with the gray hardened stuff was the CPU itself. I did what I could with it, laid down a very thin layer of the AS-C (could barely see through it overall) and reinstalled everything.

I'm surprised I'm seeing no difference whatsoever.

 

Try adding a rice or pea sided drop then let the heatsink spread it.

 

I'll try that here in a little while. thanks

 

Can anyone tell me if my temps are too high.
When playing counter strike source:

CPU: 55 degrees celcius
GPU: 93 degrees celcius

It seems really high to me. I have the laptop raised on a cooler pad with three fans in the bottom. My system specs are listed below

 

That gpu is toasty.

 

From what I've heard, doesn't the GPU have a thick thermal pad? If it does, a layer of AS5 might not be enough.

 

Don't put thermal compound on thermal pads.

 

Can anyone suggest any solution to my GPU temp problem

 

I know that and hope everyone else knows that. What I meant is that the gap may be too large to fill with AS5.

 

Which video driver are you running? I upgraded to the newest from dell.com and it upped my GPU temp by about 10-15c.

I reverted back to 167.45 and idle around 60c now.

 

I m using the 174.31. I might try that. Do you have a link for the 167.45 drivers cause on the dell site they only have 156.55?

 

I got mine at laptopvideo2go.com.

 

I tried the one of that site but it says "The NVIDIA Setup program could not locate any drivers that are compatibel with your current hardware. Setup will now exit". Maybe that version of drivers isn't compatible with my graphics card..?

 

You have to also download the modified inf file and place it into the directory of the driver you downloaded. The directory that has the setup file that installs it. You'll find the inf file right by the download link for the driver itself.

 

Thanks heaps CitizenTony my idle has dropped about 7 degrees to around 60
