somewhat dissapointing test results from glaciator

I know the difference between the top cooler and glaciator is very small but I expected the glaciator to at least outperform the cak and thermoengine. That site actually shows the thermoengine beating the glaciator with a low noise fan. To achieve that level of performance I expect that a high speed fan like the delta must have been used.

Actually you missed something and should be more careful in what you post. Frostytech First tested with the stock fans with a Delta performance of 30-33C Then added the Delta 38 for a 10C drop.

I Know that this is a hot rodding crowd But What I would like to see more reviews based on equal noise comparisons. Let's see, The Glaciator is 7-9 dBA quieter than the heat sinks with the delta fans. To reduce the delta fans to the same noise level as the GLAC you would have to slow the delta fan speed 40 to 50%. Now do your thermal performance comparison @ 3500RPM - 4000RPM Equal noise levels. Now all your other sinks with the Delta fans are 3 to 10 C hotter than the GLAC.

Thermal efficiency is different from thermal performance and is a characteristic difference that should be made when doing thermal comparisons. Noise is a signature of inefficiency. Another signature are sinks that are oversized like the swiftech.

Noise is a subjective thing one mans comfort is another's agony.

-3dBA, the sound intensity level is cut in 1/2 -3dBA 1/2 again,-3dBA 1/2 again. The GLAC is 1/12 the sound intensity level of the delta 38's.


CHEERS

you are talking about the thermoengine right? so substituting the stock fan with a delta 6800 rpm fan produces a 10c drop and the thermal performance listed for the thermoengine is shown for the delta fan but the noise level for the stock fan right? as for the glaciator they state that they observed a 3c drop in temperature when putting in the delta fan. By the way I actually own the glaciator but I am still not sure how well it performs against the otherr top hsf. overclockers.com show that the glaciator beating the swiftech 462 but frostytech shows that it doesnt even beat the cak and thermoengine (it shouldn't matter what fan the cak and thermoengine uses because the 462 beats those two sinks by a wide margin and if the glaciator is suppose to be better than the 462 it should beat the cak and thermoengine as well).

Frostytech also has the thermalright beating the swftech 462 by 3 or 4 C - My point is that at the top end all the sinks for all intent and purposes get there with overspeed fans and their assoc. noise. All are within a few degrees of each other among the top performers. To get down to those cooling levels without the noise is the differentating factor. The glac has most of them beat with the exception of the thermalRight which if you slow the speed down to a fan tip speed of 45ft. sec (equiv. RPM) would give roughly the same noise/thermal performance although The Glac would be still be a dB or 2 quieter, but from a users point of view the same.
