ThermalRight SK6 IS DA BOMB

Anyone looking for a decent cooling solution, this is it. I just got a sample from them and wow. it's nice. It might not be on the level of the Glaciator or the Swiftech, but it's close.

I've got Load Temp of 46 degrees C right now, that's w/ a 5000 rpm 60 mm fan (very quiet).

it beats the pants off my other two hs, the Global Win WBK38 and the OCZ Gladiator.

I will post prices on this HS in 1 week.
 
and, as quoted by this review, something funny is going on...

Being made of Aluminium, you would expect this Heatsink to not quite be up to that of the some of the Copper units, but looking at the Alpha PAL6035 with the same fan, performance is pretty good, and only down by a single degree under load and idle. However, looking at the MHz that I was able to overclock to, you see that the Alpha out performed this unit considerable with the Delta. The only thing I can think of capable of doing something like that would be the vertical extrusion causing the entire CPU to be cooled, putting the temps off a little, but it still seems a little strange. The Aluminium may also be playing a part by not taking up the heat as well as the copper insert in the Alpha.

Dangerous Dog Thermalright heatsink review

As typical of socket-thermistor setups, lower socket-thermistor readings does not necessarily mean higher overclocking potential or higher "real" performance.

mike i don't completely understand your point?

are you saying that just because my temps are lower w/ this hs doesn't necessarily mean that it is better than the Gladiator and the WBK??

Obviously there are problems w/ thermistor readings, but overall this hs gives me a good stability w/ very little noise.
 
according to that review, yes.

I'm sure it works well, i'm just saying not to publish any sort of review on socket-tehrmistor based readings, as in this review, because the results can clearly be misleading. The alpha ran "hotter" but overclocked better...

i know the difference between heat and temperature. the two are related but are not the same. Temperature however is measurable heat isn't. even the intell w/ the internal diodes cannot measure heat, they can only measure temperature.
 
"The alpha ran "hotter" but overclocked better"

mike did you misread the article? the sk6 ran cooler and overclocked better than the alpha pal but not by much. the alpha pal also ran cooler and overclocked better than the thermoengine. From the results its clear that the sk6 is better than the alpha pal and certainly better than the thermonengine. Overall that was definitely one of the better thermoengine reviews.
 
Mike,
how is you cooler roundup going and will it include the latest hsf like sk6 and millenium glaciator along with the long time champ the swiftech 462?

It would be cool if you could publish a partial review and then update as you receive more coolers and testing platform.
 
things have changed quite a bit in the way i've been trying to run my tests... right now i'm trying to get a hold of an athlon mp and a compatible diode reading mb to do the tests....

mrhelpful

cubic inch of aluminum at 50 degrees celsius actually holds a lot less heat than cubic inch of Copper at 50 degrees.

same holds true for ambient temperature for eg. ambient temperature of 24 degrees celsius, that in itself is basically useless knowledge, humidity is key in understanding how much heat is in the air. higher the humidity the higher the heat content of the air given a certain temperature. you will consistently find in most parts of the US that spring is the worst time of year for OC'ers because of the humidity in the air.

go w/ the taisol.

if you want an all copper one, go w/ this one or the ocz gladiator.

i really think that the glaciator is waaaayyyy to heavy, no matter what they tell you, and w/ just a clip?? at least the swiftech bolts down to the board.

just my opinion.
 
IMO this would be the performance ranking (assuming all use something as powerfull as delta black label, except for glaciator that only needs stock fan to shine:

1)462/Glaciator (need a couple more reviews before declaring the glaciator as the new champion)
2)SK6
3)taisol copper bottom/cak/pep66
 
Well Acording to AMDMB.com this is the ranking.

1.Thermalright SK-6
2.Swiftech MC-462A
3.TaiSol CGK7600092, CPUfx Core
4.KDC CPC-30370, OCZ Gladiator
5.GlobbalWin CAK-38
6.Kanie Hedgehog

So by the looks of it I can spend and average amount and get the best HS, or spend a lot and get the secodn best, or spend average and get decent. Thie seems like a clear choice. Think the Switech will come down in price since, the SK6 and Glaciator are putting the pressure on?

From what I hear the Glaciator is not a risk becuase of it's weight, they dropped a system from 5 feet and the only damage was to the case, the HSF stayed on and did not break a lug, but I don't like not being able to change fans, nor the huge waiting list for the Glaciator. I like the Taisol and may get it, but I will prolly alos get the SK6 just for the heck of it. I really do like the switech though, but it's just to darn expensive.

So does anyone have any proof to back up AMDMB review. I had heard this was a good heatsink, but to beat the switech by that much seems like something might be wrong, althought they did test the temps 3 or 4 differant ways. Any comments Mike?
 
I assume you're referring to the AMDMB review at this link.. It is a "real world" review where they test heat while running apps, browsing the 'net, gaming, etc., not under a long 100% CPU load as most other tests do. This is great and all, but what's critical to most of us is how the HSF handles heat under high stress. We want the top, not the average.

Also, something is odd about this review. They tested the CPUfx Core out at 3 degrees temp over the Swiftech MC-462A.

When others did a review (Like this one) of the CPUfx Core, they showed it performing FAR worse - In fact, it's temps were 9 degrees celcius higher than a Swiftech MC370-A.. Something isn't right here.. Before we claim the SK-6 the king, let's get some more hardcore ratings.

Thats what i was wondering, I don't know much about the SK6, but I kinda wondered how it could be the Core and Switech(I'm not saying it's not possible, I am just wondering how).
 
one tiny note. I shoulda mentioned this earlier.

the clip on the Thermalright that i got absolutely SUX. it's worse than the WBK clip if anyone wants a reference. the only way to put this on or take it off is w/ a screw driver.

my screwdriver slipped a couple of times.

anyway. this is definitely the worst clip i've faced.

of the three hs that i've had experience with, the Gladiator, WBK38 and the Thermalright i'd rank the clips as follows:

1. Gladiator, this has by far the easiest clip to put on of any hs i've ever seen. If you've read some of my other posts you will also see where i really like the concept of this clip because it rides between the fins instead of cutting a swath right in the center of the hs's like almost all other hs / clip combos. You can put this clip on using just your fingers. nice.

2. WBK, this one isn't as easy as the Gladiator, it's not bad tho. if you use a screwdriver plus grip the lil hand grip it goes on pretty easily.

3. Thermalright, this is by far the worst clip i've encountered, of course i didn't purchase this hs so i really can't complain, the models in the store may have a better clip on it. as good as the performance on this hs was, you have to wonder how much better it woulda been if it had a clip like the Gladiator that rides between the fins instead of cutting a huge path in the middle of the HS, right about where the core would be and reducing it's cooling ability.


mike208:
i agree that the thermalright probably isn't better than the Swiftech. but the CORE?? comon that hs is a joke. I don't need a review to tell me that hs sux. it's sooo anti intuitive. the idea of that hs truly. think about it, cooling is directly related to surface area. the core has wayyy to much aluminum and no real surface area. anyway. i think any of the hs mentioned would outperform the core in real life. i think i only saw one review that gave to core good marks most of the reviews find the core to be disappointing. like i said. i don't need a review to tell me that.
 
Yeah I don't know why i mentioned the core competing with the SK6, what i meant was that it beta the Switech, plus the fact that the core did as well as it did. i just think something is fishy. I am talking to the writer of the review on the other forum and he said he did try the HSF's under full load on the CPu, I am awaiting his answer as to how the load was attained and for how long.
 


<< cubic inch of aluminum at 50 degrees celsius actually holds a lot less heat than cubic inch of Copper at 50 degrees. >>



i saw that on bill nye the science guy!!! he said that a block of ice as big as a refrigerator held more heat energy than a lit match, while of course the match has a higher temperature. for example, if you tried to melt the ice with the match, the match would burn up and disinegrate way before the ice would completely melt.

just thought i'd mention that...
 
Just came from chillblast and the sk06 doesn't look as good as it once did. Go to chillblast
The sk06 is pretty good for slower proc but quickly falls behind at higher speeds. At least thats what it looks like from the graphs. Swiftec is the leader at all times. Now lets get a glaciator to review somewhere else.
 
That Chiliblast review seems a lot differant then all the other reviews I have seen, so i don't know if it is entirely accurate.
