Though too late, I'd like to express my appreciation to both of yours.
Btw, a few things for addendum.
1. SilenX Effizio's manufacturer is PCCooler in China. It's VERY popular in china. PCCooler made a HUGE variety of this design of downward air cooler(LED , No LED/Color, No Color/Fast, Slow FAN etc) .... PCCooler also made lots of inexpensive, side-blowing HDT tower coolers.
I got mine (2500RPM fan ver) at USD5 when I'm on a business travel in china. You can check below web-links for further information(in Chinese).http://www.pccooler.cn/products/pc-1/cpu-2.htmlhttp://www.pccooler.cn/products/pc/cpu/ ... 8%9F3.html
2. Deepcool, a local maker of air cooler, is second to PCCooler in china. It also made lots of inexpensive HDT tower coolers in china. I've had mediocre experience with their "high-end" air cooler in the past ........ Their low-end / budget offering is better in terms of price / performance.
