LSCool LSHS-X500 CPU Cooler for P4 S478 and AMD A64 Review

Cooling/CPU Cooling by SidneyWong @ 2005-07-26

Here is a new Company into CPU cooling promising a low profile application using copper/heatpipe technology plus light weight in a traditional way. The design utilizes three heat pipes and copper fins. Let?s find out how it performs.

Test 3 - For Fun

Test 3 - For Fun:

The last test involved modifying the X500 in a couple of ways -

Shortening the extended heat pipes.

Removing the 90mm fan bracket.

Fitting an 80 mm 3,000 Rpm LED fan.

P4 Northwood 2.8C Test Setup - Ambient temp during test ~25.1°C
CPU	P4 2.8C S478 @ 3.43 GHz 1.675 Vcore

Swiftech MCX478-V versus X500 both using the same 80mm fan @~3,000 rpm, with Chill Vent fan duct inside Lian Li PC65 case

The mod - using a tube crimping tool.

The results

I tested the X500 first knowing the 2.8C has no problem running at 245FSB using the trusted Phoenix 70. The Swiftech MCV478 failed Prime95 and had to be lowered to 240 FSB. Even at this handicap, the X500 topped out at 49°C while the Swiftech was at 55°C, a 6°C difference which is also the same temperature difference in PWM temp. The X500 overhang sits on top of the PWM circuit on the IC7 makes the difference.

I am not sure at this point if the vertical placement of the heatpipes on the IC7 setup played a role in the better performance. One thing for sure, I am keeping this heatsink in this rig for awhile.
