You are right, I missed that part : "Although in the picture above it looks like the Ninja duct goes all the way down to the motherboard, it is actually an inch above it" So I did not understand how the top fan could still cool something. The top fan is sucking some of the air from the duct near the VRMs ?cmthomson wrote:Because the VRM heat builds up in the top back corner and cooks everything.
I find it a bit contradictory to design a duct that fits very closely on the heatsink (rather than taping losely some cardboard) and not sealing it more on the motherboard side to control the airflow until it's out of the case.
Not exactly, I forgot about the VRM obviously, but I also just thought it would have been easier to cool the CPU, the MCH and the graphic card with a single top fan + duct, rather than using two parallel fans. The VRM's heatsink seems close to the case, did you thought about connecting the two with some copper ?Your ducting ideas are based on the assumption that CPU heat is the problem; this is intuitive but not borne out by experiment. The real culprit seems to be the VRM.
That's a very polite way to say I was being off-topic, which is true BTW . It's just your stack of coins in that place, that reminded me of that strange idea I had when I noticed some turbulence behind a fan even though I had cut every mesh or casing.Interesting ideas, do you think they are applicable to fans and air flow this slow?
About the noise tone, I have to thank you for finding out that website, I had great fun trying to guess the speed of a clicking fan by identifying the mechanical noise frequency as well as being able to ascertain that my screen was buzzing at the refresh rate frequency.
EDIT: Neil, Chris starts his article with
Choosing an Intel dual-core makes perfect sense as they are better in video transcoding than AMD's thanks to longer pipelines. Their dual-core have a not so bad performance/price ratio compared to AMD's dual-core when you take that into account. Obviously that's without taking into account the power consumption.I do a lot of transcoding of audio and video on my home computer, and got tired of the system being unusably slow for hours at a stretch.
