Kool Solutions Chill Vent II Deluxe CV-288 Review

Cooling/VGA & Other Cooling by jmke @ 2004-06-04

How can a piece of plastic drop your CPU temperatures by 5?C or more? Read on to find out how a plug and play air duct can increase the cooling efficiency of your system!

Test System 1

Test System 1

Case: CoolerMaster ATC-201C-SX2

CPU: P4 2.26Ghz @ 2.472Ghz at 1.5v vcore.

CPU Cooling: ThermalTake Volcano 7+ with fan running @ low speeds (~3300rpm)

Video: Hercules Radeon 9700 Pro (stock cooling)

Case fans: 2x80mm intake at front, 1x80mm outtake in back and 1x80mm outtake in top (all hooked up to a rheobus and running at 7v)

Motherboard used is an Abit TH7II and temperatures were read from the onboard sensors using Winbond Hardware Doctor.

Installation went very smoothly, only had to remove one piece of the Vent before installation, as the side panel has no ventilation holes.

The 2x40mm fans line up excellently with the AGP video card

As the Radeon 9700 Pro has no onboard video card temp sensor no results were included at this point; Do note that any increase in airflow over the video card’s hot memory chips, especially in a closed case, will always have a positive effect.

Test results

The Abit TH7II has 2 system temperature sensors, one at the bottom of the board (SYS2) and one near the CPU socket area (SYS1).

Just putting the Chill Vent into the case decreases the case temp 1-2°C and the CPU temp drops 2°C, quite well considering the fact that although this is a fully ventilated case, improvement can still be seen.

Adding the extra 80mm fan over the CPU HSF pulls more fresh air from the bottom of the case and this translates into 1°C decrease for the CPU temp. Since the hot air starts the circulate more in the case, we see the bottom sensor reporting higher temperatures.

Let’s continue with our second test system ->
