Thermalright Rolls Out AXP-90 Full Copper CPU Cooler

[GlacierNine]

So basically the better thermal characteristics of copper are most useful when you use it as a thermal transfer/interface element, to a dissipating element. Which is how copper is currently used in conventional heatsinks. We will see in benchmarks, when compared to famous low profile heatsinks already in the market.

It will be better. The question is whether it'll be better by enough of a margin for it to show up in the relatively inaccurate testing that most review outlets perform. My money is on "not really".

Where did you get that idea from? That's the same sealed fan design, just different color scheme. Speaking of Noctua, I've already replaced a fan on my L9i twice, and it's up for another replacement soon (approx. once every 2 years, which is only 3% of claimed MTBF of 150K hours).

Proof that it's a Noctua fan anywhere?

It's not a noctua fan. Noctua have never made a 92mm with that sort of design.

The NF-A9 has the stepped inlet design, which the TR fan doesn't, so it's not that.

The corners of the frame NF-B9 Redux are designed differently to the pictured fan, so it's not that either (It also has a completely different blade geometry, but I just know someone will claim that Noctua could have changed that, so let's focus on a detail that wouldn't have had to change, yet did, in order to prove that the TR fan isn't a B9)

Noctua have never made any other 92mm designs, or if they have they're not listed in "Discontinued Products" on their website, which would be unusual for them since they're very proud of their obsoleted designs.

Noctua's fans are never that quiet before A12x25==. GT1850/2150 have beat down its for years, Noctua is still like the Premium Apple's belief, haha.
There're lots of religious believer to advocate noislly, and never know Thermalright's AXP series are complete beat down Noctua's sucks low-profile coolers, and still keep quiet.

Did Thermaltake digging in my Ewaste bin ??? jk.

...No seriously, this is just 1R, 2R types of CPU cooler (minus the vapor champer plate)used back in the day. I think I still have a couple of these puppies somewhere in my garage.

It's nice to see a good old simple design again.

Add a VapoChamperPlate at the bottom.. then I'm sold!

Pointless if you can't buy it. I can't even find the AXP-100 that I wanted to buy.

It doesn't bring big benefits, no.

There used to be a bunch of voodoo people would spout about aluminium having better "emissivity", and therefore somehow being better. That's complete rubbish and you should ignore anyone spouting it.

The explanation I've always found made the most sense is this one:


If you could magically somehow heat one copper heatsink fin and one alu heatsink fin to exactly the same temperature, say 40C, in an ambient of 21C, and you blew a fan on them, the amount of heat moved off of each fin would be identical. The material used simply doesn't matter in that way. Each molecule of 21C air would pass over something 40C, pick up the same amount of heat while doing so, and then blow away into the room.

Thing is, heatsinks are not heated evenly across their whole surface like that. You can't just poke a heatpipe through a piece of metal and expect it to heat that metal evenly across it's entire surface. The heat will conduct outward from that central point and so the area next to the heatpipe will be hotter than the ends of the fins.

The longer you make the fins, the further it has to be conducted away from that heatpipe. After a certain distance, adding extra length to a fin makes no difference, because the heat simply never gets there before it's dissipated by airflow. You can increase that distance by using a material that conducts heat more quickly along it's length - like copper.

Additionally, if you do this, then the distribution of heat along that fin ends up being more even. By this principle, an all-copper heatsink can have longer fins before that impacts performance.

The greater the delta between ambient temperature, and the temperature of a dissipating element, the faster the transfer of heat between that element and the air moving across it. Since the Cu heatsink will have a greater delta over a greater portion of the fin, it therefore acts similarly to as if the heatsink had more surface area - but, and this is the big but - this is only really a relevant factor if the fin is long enough to start with, that it would have noticably uneven heat distribution due to the difference in conductivity.

For this reason, at least when the medium of heat transfer from the IHS is a heatpipe, large all-copper heatsinks do perform slightly better than large Copper/Alu heatsinks, but small heatsinks will show a smaller difference in performance between these two approaches.

Wow that is so wrong.

Considering the Difference between the C7 and C7cu was about 3C I am not expecting miracles here either.

 

[RH92]

ermm is Noctua not the one making their fans to begin with?

NOPE as far as i know only the ROG CLC has Noctua fans other than that Noctua ony make fans for their-selves !

Wow that is so wrong.

Go on then, since you're clearly so well versed, how is it wrong and what is correct?

on topic, sexy af, reminds me of the Scythe anniversary cooler way back when.

Noctua doesn't make fans for anybody.............except Noctua. Not sure where you even GOT that idea.

However, Thermalright makes VERY good fans in their own right. Thermalright was the VERY FIRST heatsink manufacturer to use copper instead of aluminum for CPU cooler heatsinks as well. They are a high quality company, but they are not, by any stretch of the imagination, on the same level as Noctua when it comes to engineering and manufacturing fans.

That's u haven't seen TR's the others product =_=, TR's through fins craft is the best in the world. They're not like Noctua just defend the expensive reflow soldering.

Take the king of aircooler, Silver Arrow IB-E Extreme to say, if mount its fan,TY-143 to NH-D15, D15 can't get more cool with higher Airflow, because it touch the ceiling.

 

[darkbreeze]

Read my post again, and maybe actually READ people's posts before responding. I didn't say a SINGLE WORD about Thermalright vs Noctua regarding heatsinks. I said "FANS".

I actually DO think Thermalright has better heatsinks, but they absolutely do not have better fans, and if you think they do, well, that just explains itself anyhow.

 

[Rx771]

Well, I think Noctua's fan only win the dynamic balance. Just buy one and test it, Its performance sacrifice for lower noise(not so much at all).

 

[darkbreeze]

Not even close. Clearly you've never used or tested a Noctua fan. Or read reviews of them. Or actually looked at the specifications, which, Noctua just happens to be about the ONLY fan manufacturer who provides TRUE specifications, not padded marketing BS.

Thermalright doesn't compete when it comes to static pressure, noise levels or overall airflow characteristics. If you can show me a review or some hard data that says otherwise, I'd be happy to take a look at it, but since I know better I'm sure that unlikely to happen.

I on the other hand, have tested, used, purchased, been sent and compared just about every decent fan out there, which is not to say that I am a professional reviewer or have the final say on what's good and what's not, but I do at least have some idea what I'm talking about and I'm not just talking out my ear hole.

As a matter of fact, I just happen to have a few fans sitting beside me on the test bench. Only a few, as I've managed to sell or give away the majority of the ones that were taking up half my space. Planning to build a small-ish anechoic chamber so that I CAN start doing some accurate and scientific fan reviews and comparisons by next summer.

Thermalright TY-143 and TY-147A 140 mm Fan Review - Overclockers

Today we will be looking at two of Thermalright’s 140 mm PWM fans, the TY-143 and the TY-147A. If you have been following 140 mm fans at all, you know that Thermalright’s TY series of PWM fans are said to be among the best. Are They? Thermalright has sent us a pair of each to evaluate. Let us see.

I can't be the only person who finds that chart damn near unreadable, right?

 

[darkbreeze]

I can make charts up too, they don't mean anything without some kind of empirical data to back them up AND they need to come from a reliable, trustworthy reviewer because half the people out there "reviewing" hardware literally don't know an anechoic chamber from a subway bathroom. And let's face it, about a third of the population on this planet are dishonest to the point of being a waste of air.
