Intel P4 Aircooling - Heatsink Roundup Q1 2005

Cooling/CPU Cooling by jmke @ 2005-03-01

In part two of our roundup we compare 11 different P4 heatsinks made by Thermalright, Spire, Primecooler, Zalman, Evercool, Vantec and Titan. Using different fans at low and high speed we try to find the best bang for the buck, best performer and most silent HSF combo out there.

Evercool NW11F-CL825

Evercool NW11F-CL825:
Supplied by: Evercool

This is one of Evercool's more compact units, featuring a combination of copper and aluminum it's a low cost heatsink with an 80mm LED-fan fitted on top; it surely has the looks, but does it perform?

Specifications :

This heatsink can be installed on:

Madshrimps (c)

* aluminum heatsink with large fins with round copper insert in the middle
* 80mm fan support (LED-fan included: 3850@ <37dBA)
* FAN controller included (can be in spare PCI slot)

Full specifications at product's webpage.

In the Box

In the box I found the heatsink, FAN & mounting bracket and a small amount of thermal paste. According to the product’s specs page there should be a fan controller, but I did not find one.

Construction :

A full copper center is surrounded by a series of aluminum fins, it made me think of a Dr. Thermal heatsink. The base of the Evercool is smooth with only a few machine lapping traces.

Installation :

The 80mm fan is installed onto a separate plastic bracket which then needs to be pushed onto the heatsink and the clips on each side hook onto the Intel retention bracket, plug and play; The LED fan gives of a nice bright light and with the finger guard on top displays quite a beautiful pattern.

I did run into a small problem with the heatsink itself, the retention bracket I’m using is fixed in its place by 4 plastic pushpins, the Evercool HSF rested on those, instead of the CPU, making insufficient contact; after cutting the mini-push pins in half I was able to make the heatsink fit without issue. Making a small (2-3mm) indent on the heatsink itself at each side will prevent possible compatibility problems.

Performance and Noise :

The Evercool unit meets some stiff competition in the 80mm fan “league” , XP-90 and SP-94 from Thermalright are included in the comparison:

With the stock fan the unit performs identical to the Intel retail HSF at a slightly higher noise level; not too impressive; With the 80mm Delta fan it does a bit better, even at “Low” fan speed it keeps the CPU “cool” enough to keep running and is barely audible. At “High” fan speed it trails the XP-90 by ~3°C which can hardly be called bad, but the generated noise is much higher!

Where the unit does shine is in the price department, I’ve seen it for sale for less then $20, making it a very low budget friendly solution, however it’s hard to recommend due to the below par performance.
