Revised Corsair Enthusiast Series PSUs Can Run Completely Fanless

[btarunr]

Corsair unveiled a trio of Enthusiast Series V2 (TX-series) PSUs in Japan, which feature Hybrid Silent Fan Control, a revised thermal management measure that spins down the fan completely under low loads, and begins to spin it up only after a thermal/load threshold is crossed. These PSUs feature the same casing as the modular TX-series V2 models (such as TX-750M), but feature completely fixed cabling. Among the PSUs launched are the new (improved) TX-650 (CP-9020038-JP), TX-750 (CP-9020042-JP), and TX-850 (CP-9020043-JP). The three models are 80 Plus Bronze-compliant, and otherwise feature the same specifications as the Enthusiast Series V2 models in the market, elsewhere.

That's great but when are they actually going to release the rest of the updated AX series with the "i" suffix? I've been holding out my PC upgrade because of it because I don't want my new parts to run on a 2nd grade unit

You won't notice the difference. There are loads of great PSUs on sale today.

Out of interest, is this hybrid feature available on any other Corsair PSUs, or just TX?

My current Corsair AX850 already does this. Pretty sure Seasonic PSUs have done this for years, and not just their X-series either. My guess is this is new for the TX-series, but definitely not new for Corsair or PSUs in general.

Some psu's from other brands have done this for ages. Way to go Corsair.

In what way is the cabling "fixed"?

 

[blibba]

In what way is the cabling "fixed"?

It's not modular. It's attached to the PSU.

Ok, cool. It seemed to read as if a cabling fault had been fixed, which is what puzzled me, lol.

Fanless or semi-fanless?

The title and the news content conflict with each other; the title says it's completely fanless, but the content says that it "begins to spin ... up only after a thermal/load threshold is crossed".

Sounds like a bad way to burn up a PSU.

The title says that they CAN (as opposed to do) run completely fanless. As in, under certain circumstances. This is entirely consistent with the truth.

The thermal threshold for the passive mode will be such that the lifetime of the components is not affected. This is not a new technology.

This is a truth I am not unaware of. If you know more about this please elaborate.

Read the original post, then...

 

[duneworld]

The original post says they are semi-fanless, this means the fan doesn't spin throughout it's load range. If a PSU was completely fanless, then it would either not have a fan or it would never spin.
So like I said the thread title and the content of the post contradict each other.

There's no conflict. The article says it can run completely fanless - and it can at low loads. If it had said always, then you'd have been right.

My understanding of 'run completely fanless' was that it would do 750W fanless.

Well that's an entirely arbitrary understanding. Is your understanding of the word "hello" actually "I'm an Iguana"?

The rest of us (mostly) communicate using a commonly accepted, dictionary defined understanding of language, which we tend to find makes things way easier.

 

[duneworld]

I am actually trying to be helpful, rather than argumentative, so I'd appreciate it if you could use some decorum when writing your responses to me, I find that you insinuating that I would misinterpret the word 'hello' somewhat insulting. And I have insulted no one.

So you're telling me that if you read "Revised Corsair Enthusiast Series PSUs Can Run Completely Fanless", without reading anything else or having any other information you would think/know that these PSUs are only fanless at low loads?

I think that if btarunr had added the words 'at low loads' at the end of his news title then none of this would have happened.

I was merely providing an example of the ridiculousness of defining language at your own whim.

Almost every news title on the site could be made to contain more information with a longer title. For example, the title "Sony PlayStation 4 "Orbis" Kits Shipping to Developers, Powered by AMD A10 APU" misses out any discussion of hybrid crossfire. On many sites, news titles are far more sensational, and designed to draw you in to read something actually less impressive than you first imagined.

Your original assertion was that "the title and the news content conflict with each other". This is not the case.

I think that if you had not posted something that wasn't true, none of this would have happened.

Or my understanding of the English language when I have a dictionary and I consult it quite regularly.

He didn't have to make the title longer either. He could have phrased it thus: "Revised Corsair Enthusiast Series PSUs are now semi-fanless".
8 words vs 9.

It would seem to be syntax rather than semantics that you have an issue with.

How long do you expect the man to spend thinking about every news title? I think it's fine as it is. Nobody else had an issue with it. If you want your news titled by someone else, go get it somewhere else.

 

[duneworld]

Actually my problem is that too often I try to correct other people's mistakes, or what I perceive to be other people's mistakes. I only realised this problem after I started participating in this thread. This thread wasn't entirely responsible for that realisation btw.

Can you not understand how the news title could be 'misinterpreted' the way I have described above?
For the record I can understand how you have come to interpret the news title in the way you have described above.

You can't say that no one else had an issue with it just because no one else has posted in this thread.

But by including old technology into their products, it can be marketed as new technology. Moar marketing = Moar sales.

I don't understand why they keep on inventing hot water. I'm running my HX750 using ultra silent Noiseblocker fan for ages now and it's awesome. Sure the fan was expensive but it cools it just fine and it's so silent you can only hear it by having ear 5cm away from the fan. Anything further and you won't be able to hear it.

So, why don't they stick a quality fan in the PSU's in the first palce and no one would even care between fan and fanless modes if it's already so silent you can't even hear it...

I agree, put a decent fan in it and have it run all the time. Having fans switch on and off introduces a discontinuity in the temperature profile of the PSU and also noise, which is undesirable.

Also, something which no one is considering, is that mechanical devices tend to seize up if standing still for a long time. Therefore, one can imagine the scenario where the fan doesn't come on for a whole year. Then, when the user upgrades from integrated graphics to a GTX 680 or similar, the demand on the PSU goes up and it tries to start the fan. The following could then happen:

- The fan doesn't rotate, eventually overheating, along with the PSU overheating. Funny "hot" smells are noticed from the PSU and it's eventually damaged and stops working

- The fan rotates, but makes a bad noise due to a partially seized and possibly dried out bearing. The noise is loud and irritating, quieting down after several minutes, but not going away completely. The fan does this at every startup

- It runs just fine, like the PSU was new

I think the second option is most likely if the fan was allowed to stand for so long.
