Thermaltake Big Typhoon VX: Does VX Rule Cooling?

CPU Cooling Test Configuration
The standard test bed for cooling tests uses an EVGA NVIDIA 680i SLI motherboard. This is primarily based on the consistent test results on this board and the NVIDIA Monitor temperature measurement utility, which is part of the nTune program.
NVIDIA Monitor has a drop-down pane for temperature measurement which reports CPU, System, and GPU results. Reviews at this point will concentrate primarily on CPU temperature. In addition to the real-time temperature measurement, NVIDIA Monitor also has a logging feature which can record temperature to a file in standard increments (we selected every 4 seconds). This allows recording of temperatures during testing and play back, for example, of stress test results that can then be examined when the stress tests are completed. There is also the handy reference of speeds and voltages in the top pane to confirm the test setup.
NVIDIA Monitor was compared to test results from the Intel TAT (Thermal Analysis Tool). Intel TAT CPU portions do function properly on the EVGA 680i motherboard, but the chipset-specific features do not operate as they should. Idle temperatures in TAT were in line with measured idle temps with NVIDIA Monitor. The CPU stress testing with TAT pushing both cores showed TAT stress temps at 80% CPU usage roughly corresponded to temps reported in our real-world gaming benchmark.
Other components in the cooling test bed are generally the same as those used in our motherboard and memory test bed:
All cooling tests are run with the components mounted in a standard mid-tower case. The idle and stress temperature tests are run with the case closed and standing as it would in most home setups. We do not use auxiliary fans in the test cooling case, except for the Northbridge fan attached to the 680i for overclocking.
Thermaltake provided a small packet of white thermal compound with the VX. We tested the VX with our standard premium silver-colored thermal compound. In our experience the thermal compound used makes little to no difference in cooling test results. This is particularly true now that processors ship with a large manufacturer-installed heatspreader. Our current test procedure uses this standard high-quality silver-colored thermal paste for all cooler reviews.
We first tested the stock Intel cooler at standard X6800 speed, measuring the CPU temperature at idle and while the CPU was being stressed. We stressed the CPU by running continuous loops of the Far Cry River demo. The same tests were repeated at the highest stable overclock we could achieve with the stock cooler. Stable in this case meant the ability to handle our Far Cry looping for at least 30 minutes.
The same benchmarks were then run on the cooler under test at stock, highest stock cooler OC speed (3.73GHz), and the highest OC that could be achieved in the same setup with the cooler being tested. This allows measurement of the cooling efficiency of the test unit compared to stock and the improvement in overclocking capabilities, if any, from using the test cooler.
Noise Levels
In addition to cooling efficiency and overclocking abilities, users shopping for CPU cooling solutions may also be interested in the noise levels of the cooling devices they are considering. Noise levels are measured with the case open on its side and are measured using a C.E.M. DT-8850 Sound Level meter. This meter allows accurate sound level measurements from 35b dB to 130 dB with a resolution of 0.1 dB and an accuracy of 1.5 dB. This is sufficient for our needs in these tests, as measurement starts at the level of a relatively quiet room. Our own test room, with all computers and fans turned off, has a noise level of 36.4 dB.
Our procedures for measuring cooling system noise are described on the page reporting measured noise results comparing the stock Intel cooler and recently tested CPU coolers to the Thermaltake Big Typhoon VX.

AnandTech never reviewed the BT VX before, and when it did, it had concluded that this cooler is bad, why just coz another type of coolers are better !!the problem with this review is that the Cooler is very good, but the conclution did not give it what it deserve. it just said that a 90 degree mounted fans coolers are better.. ok I agree and thanks for AT for this, infact I just knows that thanks to Anand, but the problem is where the conclution for the VX as a cooler not as heatpipes tower vs. downfacing fans coolers comparision..

We did NOT say the BT was a bad cooler. We talked about the performance being the best for this type of cooler and the good things about installation and design. Don't you think It would be unfair to say the VX topped our perfromance list when it didn't?In our conclusion we also said "There is no doubt the Big Typhoon VX is, along with the Cooler Master GeminII, the best of the down-facing cooler designs." and "While performance does not top our charts, there are still many things to like about the Thermaltake Big Typhoon VX. It is one of the easiest to mount coolers we have ever tested. While we do have concerns about two pounds being supported by Intel-style push clips, the installation itself is easy and does not require you to remove your motherboard. It is equally easy if you are mounting the VX on an AMD processor.
The attached fan speed control is also very useful on the Big Typhoon VX, particularly since it is attached to a very high-output fan capable of 86.5CFM at high speed."
I don't think this is saying the cooler is bad.

It isn't a bad cooler at all. However, there are some ways to make it perform well under its potential.First off, it needs a side air duct or side case fan blowing down onto it so it can breathe efficiently. Give it that, and it will be far less likely to cycle hot air through its fins at high operating temperatures.
Secondly, it does need a fairly strong exhaust fan.
The Big Typhoon (standard and VX) has put in impressive showings on open-air testbeds that showcase its potential strengths. In restricted air environments, you wind up with a cooler that can not efficiently pull cool air into the case or move hot air out of the case (the latter of which is a nice feature of a properly-positioned L-shaped cooler).
I managed to get good operation out of mine using a Centurion 5. All I did was pull the side air duct off (the VX is too big to be mounted with that thing still screwed on to the side of the case) and use the VX's included fan as an exhaust. Then I put a Silverstone FM-121 on the VX itself. It serves as the intake fan for the case, cooling everything but the HDDs, plus the HSF fan as well. The exhaust fan more or less takes care of everything else. It's a simple and cheap solution that cools very well. In contrast, an L-shaped cooler in a similar setup would have problems due to there being no strong or direct intake . . . it would essentially be pulling air from inside the case which would, ideally, pull cool air from outside the case through various vents, but for the most part, it would also be pulling in air heated by other system components.
All this might account for why the VX did so well at idle but so poorly at load.

My Tuniq on an E6600 in a Centurion 5 idles at 27-28*C and goes to 33-34 at load with ambient around 75*F and just the stock case fans (80mm at front blowing in over hard drives, 120mm at back blowing out). The Tuniq is set to ~1350RPM.
