Summary: We were very wary before testing Thermaltake ISGC-200, because of the low performance achieved by the smaller cooler from this series,
. Our results, however, show that ISGC-200 is far better than its "little brother" on cooling performance. Besides that, it is quieter, even though they use the same fan, probably because of the sandwich design.
Its cooling performance is good, but not as good as the best coolers we tested so far.
Summary: The ISGC-200 heatsink itself stands 140mm tall, weighs 470 grams and accommodates one 92mm PWM fan that spins at 600~1600 RPM. If I didn't know better I'd say the ISGC-200 was released for Intel's new socket 1156 formfactor processors.
