Looking at the above image I'm not too sure about this. Reaching FSB clock speeds above 300MHz my northbridge gets pretty hot with active cooling. Note that the new silent OTES is on the Intel 955X chipset board called the ABIT AW8. Last time I saw this board it was running the orange PCB. I really dig on the black PCB shown in the photos on the PR. It will be fun to see what the temperatures will be with this new cooling solution. Since this PR says this technology will be out in May, I'm assuming that will be the time frame for the launch of the ABIT AW8 also.
News Source: ABIT TaiwanMonday, April 25, 2005 – ABIT Engineering has done it again; but unlike the high performance coolers like OTES™, OTES AeroFlow™ and Dual OTES™ before it, this one won't be making a sound.
Today ABIT is proud to announce its latest innovation, the Silent OTES™ (Silent Outside Thermal Exhaust System), a device specifically designed to silently cool the motherboard's North Bridge chipset.
Silent OTES uses ABIT-designed heatpipe technology to transfer unwanted heat from the North Bridge to the fins of the Collection Module. From there, heat is exhausted outside of the case by air flowing from the CPU fan. The result, a totally silent platform offering excellent cooling efficiency while utilizing the existing CPU fan, ultimately providing enhanced performance, stability and a quieter experience for the end user.
The cooling system is derived from the finest materials to ensure excellent cooling performance. The North Bridge comes in contact with a high-grade aluminum heatsink with an all-copper base, which is fastened securely with screws to ensure maximum contact for heat transfer. Pure red copper fins on the Collection Module are angled for optimum air flow, and utilizing existing airflow from the CPU fan, deliver excellent cooling with minimal noise thanks to their large surface area.
"Silent OTES will be a great boon for performance users who need optimal cooling a quiet environment," notes ABIT Product Marketing Manager Michael Chen. "Eight months in development, Silent OTES follows in ABIT's tradition of bringing innovative solutions to users world wide."
The first motherboards to feature ABIT's patent pending Q-OTES technology will be announced in May.
