Re: [H] Overheating laptop
Well, I suppose I reacted to the "possible" crack in a sealed tube of liquid. I thought the pipes were solid. H.. :) I do have experience with solid heatpipes. Yes, it was years ago. If all the 'new' ones use liquid, this is a good improvement. I can deal with this forward progress.. :) Thank you for bringing me up to speed about 'heatpipes.' Great share. Now I'm a bit more forward. And, in the future, I will search for heatpipe-type cooler solutions. Right now. Don't need any help. It's all good here with ThermalRight. My share holds. Believe the heatsink may be toast. Best, Duncan At 03:43 01/31/2008 +, you wrote: On 31 Jan 2008, at 01:57, DHSinclair wrote: Well, I do not know the actual construction of the 'suspect' heatsink.
