Lowering temp for XPS 1647

Hey all, I was wondering if anyone had suggestions on ways to lower the temp of my XPS 1647.

I'm planning on getting a laptop cooler, either a Zalman NC2000 or Cryo LX (any suggestions?) and I've heard good things about undervolting. Is undervolting viable for the 1647 or dual cores? And does anyone have more suggestions?

Thanks!

 

Re-do your thermal compound (both CPU and GPU). There is a video linked on this Forum that can help guide you. Use GC Extreme or AS5 (I'd suggest GC Extreme).

What CPU do you have in your 1647? I'm curious, what is your primary motivation to lower the temperature and your expectations?

 

Ah yes, thanks for the quick reply. I'll look into doing that.

I have the Core i5-540M. I'll be using the laptop as a desktop replacement, and that will include playing some games on and off. I don't know what kind of expectations to have, I just want to keep the laptop healthy and last as long as possible.

 

With the switch from Core 2 Duo to Core i, Intel has eliminated the ability of software to change the core voltage so you can't cool down your CPU that way like you used to be able to do. About all you're able to do is to reduce the speed of the CPU by reducing the multiplier or turning off Turbo Boost to lower its temperature. This isn't much of a solution.

 

Does this actually work? I thought that Dell used thermal pads anyway. Or is the paste much better than this? Right now my 1640 is idling in the low 40's for the CPU and the low 50's for the GPU depending on the temperature outside and the power saving mode (goes a bit lower if on power saver over night).

 

There is a Thread focused on this.. I am trying to keep track of before/after...

Using a good compound will do wonders for temps. My system (see sig) uses AS5 and idles around 45C for CPU/GPU, and under extreme load just tops 70C. Without AS5 the temps go much higher under load, into the 80's and 90's.

 

Which technique did you apply to put the thermal paste, like line 1 or cue one or whatever?

 

are u sure about the fact that i5/i7 models can't be undervolted? that wud be a shame...

 

MSR 0x199 is the register that used to contain both the FID and VID. That's the requested multiplier and the requested voltage. Starting with the Core i7 desktop CPUs, this register was changed. This register is still used to set the multiplier but the voltage information was removed. There is some older software that tries to interpret the information in this register as voltage and even lets you change this register and might make you think that it is changing voltage but all it does on these new CPUs is screw up the multiplier.
