How to: Improve your XPS M1330 Cooling

The M911? Are you referring to the A2 version of the heatsink and fan assembly?

 

does anyone recommending bending down the heat pipe so that it is pressed against the GPU?

 

I did with good results. It must be done precisely though, or it will cause more problems then it will help.

 

Could u share ur technique?which factors u considered as u bent d heatpipe to perfection.

 

Did not have much technique.
I used a shim still, about .5mm, and I did a lot of trial and error.
Using TINY amount of thermal grease, you can tell if you're making a perfectly flat contact.

 

hmm ok.. metaloffcuts ain't replying to my enquiry on delivery status. ordered on april fool's and it's no joke. already paid.

 

OK i just did the mod> i can't get past 71 celcius now.

 

Hi, all. Recently I with my friend have implemented this mod: http://forum.tabletpcreview.com/showthread.php?t=8875. And I'm wandering, if such thing would make my XPS 1330 cooler... Anyone tried?

 

Ummmm yeah. Generally better thermal paste and a lapped HSF will improve temps, regardless of the implementation.

 

Just cleaned black paint of the heatsink. If there is a drop in temperature, I haven't noticed it.

Anyway, when idling (already with copper mod):
CPU: 35
GPU: 52

Under load (AtiTool):
GPU: 70
CPU: 49

 

Pretty nice temps, congrats.

 

Thanks. And thank you for the idea and instructions on copper mod.

 

My xps1330's extended warranty expired in october 2009, at that time Dell had replaced the mobo on-site twice. In January 2010 the 8400 gpu fried again so I contacted Dell who advised me I'd be required to send the laptop to Dell and pay $600 for the repair. I asked if the 3100 Intel chipset m/b could be used this time & was told no, the 8400 gpu was the only replacement m/b option available. I left it a couple of weeks, intending to scrap the xps1330 & use it for parts but then I decided to give consumer affairs a call - they suggested I try calling Dell one more time. Once I mentioned consumer affairs were now involved, even though the warranty is expired a Dell tech was onsite the next day. I got him to compare the old & new m/b and heat sinks etc, all identical, so I let him go ahead & replace the m/b, then I recorded gpu & cpu temps once the 1330 was up & running again, gpu was 69C and cpu was 44C & 45C at idle. Once the tech was gone I turned off the laprop & went to my hardware store & bought a 2" length of copper pipe with a wall thickness of just over 1mm. I cut a side of the pipe lengthwise with an angle grinder, opened it up, flattened it out with a hammer, cut out a 15mm x 15mm piece with the grinder, used wet & dry sandpaper on a piece of glass to get it nice n flat, then proceeded to use it in the copper mod - no problems, heat reductions of around 14C at idle - thanks guys, great mod
