What do YOU think are the best 140mm LGA1700 air coolers?

[RevGAM]

I'd like to know for both single and dual tower. I'll be testing fans on it with a 12700K on my Asus TG H670 Pro wifi D4. It MUST designed for 140mm fans. Multiple options is great!

 

Related questions:

• Are there coolers that are made for 200mm fans?
• If a fan's inner diameter exceeds the edges of the cooler's heatsink, at what distance will there be a loss in heat dissipation? I ask since the outside of a heatsink should get hot, too, and heatsinks designed to exactly match the square dimensions of fans neither have that byflow nor cooling of the corners to the fullest degree that an oversized fan would.
• If I wanted to mount a larger (LxW) fan on a smaller heatsink, obviously the fan clips aren't going to work. What would be the best way to attach a fan in that situation without damaging the heatsink fins (and fan)?

Size isn't everything.

 

A 140 mm fan may have higher CFM, but because the fan is larger and heavier, they often don't have enough power to produce the same air pressure as a 120mm.

 

This is a problem that will affect a fan's performance when they need to push air though the cooler fin stack.

 

This is also one of many reasons that why a 120mm DeepCool AK620 can almost match a 140mm NH-D15 or 140mm Deepcool Assassin III.

 

As far as I aware 200mm CPU coolers never existed given they can't fit most cases. Even 140mm may have problem.

 

Mounting a larger fan on to a smaller cooler is not recommend, because the small amount of diameter you gained from the edges of fin stack often lost with a larger hub.

A larger hub means less air through the hottest part of the fin stack. 

 

Also, depend on the cooler you started with, a larger fan may cause worse performance if the case of the fan went over the fin stack. This is caused by flow love to find path of shortest resistance, so instead of going though the finstack, they go out from sides of the finstack. So center-back of the finstack have reduced flow.

I understand and thank you for the info. However, that doesn't change the fact that I need recommendations for 140mm coolers because I'm testing 140mm fans on them. I certainly can't mount them on my U12A.

A nhd15 and call it a day

Scythe Susanoo can fit a 200mm fan.

Interesting, but I can't find the SCSO-1000 anywhere. Not even on the Scythe website. It's discontinued, too. And no LGA1700.

Noctua NH-C14S

Honestly the NH-C14S might be the best for this if you're okay with the parallel mount. Otherwise you might be better running the fans on a 140mm single AIO with a heat source on the block.

Thermalright FC140.

Well, I want to be able to approximate the U12A for 140s. Aren't rads denser than heatsinks?

I knew you'd chose that one.

I told you all that I was a huge Thermalright fanboy. Been that way for over 20 years

 

Not much different than a Noctua fanboy, just a little louder

 

Its also got more mass, and more cooling potential than a D15.

Will the fan clips on this one work with standard size fans? that's my biggest concern.

Yeah I have used my FC140 with NF-A14 and NF-F12 3K fans with no problem. I now use NF-A14 3K and T30 together when I use FC140.

apparently the NH-U14S is compatible with 140x140x25 so that's a single tower option.

@freeagent@TeraSeraph@jaslion@Ralf@Supersonicwolfe

Ok, so there are plenty of others. Additionally, no one has answered my other two questions.

 

Single Tower:

Noctua C14S, U14S

 

Dual Tower:

Noctua D15

Thermalright Frost Commander 140

 

Surely there are others? DeepCool Assassin 4, AS500 PLUS or Tower? Cryorig R5?

200 x 200 heatexchangers for cars? tbh I'm wondering why you want to test these on a heatsink? They're designed as case fans with low pressure performance.

It starts to effect things as soon as there's pressure leakage. adding foam gaskets top and bottom flush with the fin stack will solve the bypass issue.

holding the fan on a separate frame that is then brought up to the heat sink is an option, this way there's no damage to either .

That's a fair point. I'll have to figure out something else, since the Extech AN300 doesn't look good.

So the byflow won't benefit the cooler at all? Then why put 140s on coolers like the D15 when there's byflow?

I'll keep that in mind, but then there's the issue of byflow, and I've got no skills in 3D design to 3D print a trumpet or adapter.

I've given up looking for better anemometers. My cheapo BTmeter is actually reading more accurately than another wand style unit I just got.

There's a difference between what you want for a live PC vs for more sterile lab testing. I am on the side of eliminating variables for cleaner data. By flow is usually good, and with a 140mm the by flow will cool the ram and VRM. The larger heatsinks take advantage of the greater airflow of a 140mm fan. Even if you miss a little of the air the majority of the heat pipes are getting cooled in the highest flow areas of the heatsink.

Out of those that you listed maybe the Deep Ass?
