Looks like a good deal, what do you guys think?

Unique Low-Profile Cooler With Twin Fans Claims It Can Chill AMD And Intel CPUs Up To 265W

The Jiushark Diamond JF13K uses dual 120mm fans, seven heatpipes, and a diamond shaped radiator to cool performance CPUs with a height of just 92mm.

First, note that is not really a review but a re-statement of the marketing hype.

It "claims" it is tall enough to clear motherboard components - I would want a moneyback guarantee, no questions asked, before buying.

Note also, it comes with 120mm fans that are only 15mm thick. So with short (compared to 140mm) blades that are not vary wide (compared to standard 25mm thick fans), that means the fans will have to spin considerably faster to move the same amount of air as typical 140/25mm fans. Faster speeds means more noise. And I hate fan noise.

It usually speaks volumes - very loudly - when marketing hype does NOT mention something. And there is no mention whatsoever about fan noise in that article.

Complaining about fans on an aircooler is kinda special, particularly when you don't express any concern about overall cooler height it really shouldn't be hard to just swap them out for some regular 120mm ...

 

[Bill_Bright]

Huh? What are you talking about?

Where did I "complain" about fans on an aircooler. I merely stated facts or pointed out omissions of fact.

Do note the OP asked for opinions.

And stating I didn't express any concern right after you quoted me expressing concern about height is just trollish nonsense from a new user trying to make a splash by criticizing others instead of actually contributing to the thread.

Looks like a MF'er to install. But uses the push pin design like stock coolers, those things suck.
Top down blower design, at it's defense can claim lower board temps and probably true enough if the pressure is decent.
The fans that it comes with obviously can be upgraded. So at least a non issue there, looks like easy fan installation without having to remove the cooler.

The title is misleading as well. This cooler doesn't "Chill" anything, I don't see any Peltiers installed. It's just another typical heat sink.

Claiming 265w might be brave though. I'm skeptical, but a proper review would be interesting for sure.

 

[Bill_Bright]

but a proper review would be interesting for sure.

I agree. I personally don't have a problem with top down fan directions. As you note, they tend to offer good cooling to sensitive components surrounding the socket. They also may interfere less with desired front to back flow of cool air through cases.

I see no point in commenting on "overall cooler height" on a cooler marketed as a "low profile cooler". My concerns, as I expressed, is motherboard component clearance - and fan noise.

Any why anyone would buy a low profile cooler just to spend extra to swap out the 15mm thin fans with standard 25mm fans, as suggested above, is just baffling to me. And they would still be 120mm fans which, as a general rule, have to spin faster (therefor louder) than a 140mm of equal quality to move the same amount of air.

But uses the push pin design like stock coolers, those things suck.

Except with stock coolers, you push then make a 1/4 turn to lock in place. I don't see how these could be locked in place. I tried to find the user guide. Sadly, if you visit the product's website and click on Data download and Product videos for more information, you get nothing. And for "Service Support", it says, "No information found!"

So is that complaining? Yup! Oh well.

Lol, I don't think there's complaining here. More so educated factual statements with the information we do have available, which doesn't seem like a lot.

I'm interested in the base size and material make up also. I'm assuming copper, but there could be aluminum there which would lower the mass. But with a 265w claim, assumption is copper and 50mm with that many heat pipes.

Some people have fan choices and might always just replace cooler fans.... well just because. They might like higher static pressure over cfm, or like you want lower dB fans.

I'm a firm believer in reviews where the person would try different fans for maximize the performance of the cooler design.

As far as thickness, there's still fan choices that would fit the low profile design, but may be quieter, better cfm, better static pressure ect ect. But with most cheap coolers, the 2 bearing fans are even cheaper.

I disagree with that. I see no point - from the consumer, potential buyer's point of view - for a professional review of an "off the shelf" product if the reviewer ends up modifying the product with custom modifications unintended by the maker, and which only a small handful (if that) of potential buyers would be interested in.

When I read reviews, I want to see what the reviewer says about THAT product, as it comes from the factory, so I can compare it - on a level playing field - with other reviews and competing products.

"IF" that cooler was designed for and marketed to allow users to pick and choose different fans, then fine. But this cooler is not.

I see your point. And of course the review should be based on it's stock configuration.

But we can't act like people don't swap fans on their coolers. It's a thing, it does happen often enough to mention it.

But this cooler has poor marketing from the get go. So far this thread is marketing the cooler better than anything else.

 

[Bill_Bright]

Who's doing that? Surely not me. I've been making custom modifications to computer hardware going way WAY back to my Commodore 64 days when I modified a 1541 floppy drive to device 9 (from the default 8) so I could have two drives at once. I don't overclock anymore because there's no challenge (risk) to it. Back in my day, to overclock, you had to physically cut motherboard circuit runs and solder in jumpers. Talk about destroying any chance of a warranty return!

And for coolers specifically, big hunks of metal don't go bad. But ALL fan bearings go bad - eventually. So sure, I have replaced many fans - even some perfectly good fans just to replace with quieter fans - since I really hate fan noise. IIRC, that was only with OEM coolers since back in the day, quiet fans were not a priority. Fortunately, both AMD and Intel include OEM fans that are much quieter than those in the past. But that's for a different discussion.

I have never purchased a new cooler with the intention of immediately replacing the fan. That makes no sense to me. Instead, I would do more research and buy a different fan that met my needs from the start.

it does happen often enough to mention it.

In forums? Sure. In proper reviews? No. But again, the link above to this cooler is not a "proper" review but a simple restating of the marketing hype. I will quickly add that Hothardware.com is not calling it a review either - but rather a "news" announcement (11th down) of a new product.

But this cooler has poor marketing from the get go.

Now on that we totally agree.

YOU are one in millions. Because you don't do something, doesn't mean there are not others doing it.
Here is ONLY a techpower up search for 2 key words only " fan upgrade " - You may view these results at your leisure, It's only 8 pages of results.

Sometimes a fan is replaced because it's garbage. You must think a 40$ heat sink comes with quality fans, I'd beg to differ.
People do all kinds of things that don't make sense to Bill Bright himself, but some of it may make sense to someone that has a different opinion. No?
AGAIN - Another search at a bigger forum dedicated to this kind of stuff.

Search results for query: Should I upgrade my fan?

www.overclock.net

Yes, in tech forums advertisement by search engine will pop up this very thread we are typing in.
Something where Redit is huge for this type of thing.

Word of mouth isn't in the newspaper and television only anymore Bill. You of all people should know that. Reviews are the best for of information the masses look for. If this product is searched before purchase (God I hope people do that first...) this is advertisement. Poor advertisement maybe, but even bad advertising can sometimes produce the best results.

But I digress, a consumer shouldn't "have to" make changes to a product, but as a Diesel technician, welder fabricator myself, I know for a fact that sometimes the engineer's designs are crap at release time.

You sure like to twist things around to justify your claims, huh?

I never said or implied there are not others doing it.

Just because YOU do something, doesn't mean everyone, or even most are.

While TPU and OCN are popular sites, contrary to what you want everyone to believe, they do not represent the majority of computer users.

It seems you have no problem expressing your own opinion, but if someone expresses another, you have no problem criticizing them personally. Sad.

I'm done here.

I'm just correcting the statements that you use the terms "I" as if speaking for everyone which is on the contrary.

Don't like it, don't quote me. Simple procedure.

 

[Bill_Bright]

you use the terms "I" as if speaking for everyone

LOL There you go again.

Since when does "I", clearly a singular noun, suggest everyone? That's just plain silly. If "I" (as in just "me") meant everyone, "I" (again, meaning just "me") would have said everyone, or all, or at least "we".

You need to look in the mirror, Bud. I note YOU quoted me where "I" repeatedly said what "I" would do for "me" with "my" research, then YOU saying (my bold underline added),

we can't act like people

So clearly it is not "me" pretending to speak for others. Nor did I resort to personally criticizing you when "we" did disagree. I simply expressed why "I" disagreed. My point, btw, you said you saw.

So no, you were not correcting my statements, you were twisting my comments around to something I did not say, then claim I was wrong. That's just sad, and deceptive - and certainly not helpful to the OP.

So, to prevent further degradation of this thread, and because I need to get the grill ready for some really nice NY strips, I really am done here - the last word is all yours.

Quit quoting me. I'm not interested in all the off topic stuff.

People swap fans on coolers. Not sure what's so hard to understand here Bill.

 

[freeagent]

I swap fans all the time, and there are many guys just like me out there, and I bet more than half of them don't post on tech forums.

Relax Bill, no need to badger.

 

[sLowEnd]

The design reminds me of the old Coolermaster GeminII

Cooler Master GeminII: Performer or Poser?

[freeagent]

There is no way that can cool 265w. At least not 265 modern watts, similar to oldschool watts.. but through a much smaller, denser package.

I have a hard time with 240w PPT through 7nm and my coolers.

 

[Bill_Bright]

I've done my share of swapping too. Not my point. All I was saying is, IMO, professional comparison reviewers don't need to be reviewing with alternative fan solutions (since there are 1000s of possibilities), unless the cooler is designed for, and marketed as a cooler with interchangeable fans. I just don't see that capability as something readers looking at $40 HSF assemblies are looking for.

Relax Bill, no need to badger.

Not sure I am doing the badgering as I was trying to keep it impersonal. But okay.
