Trying to decide. I have an R5 3600 and the stock cooler keeps it around 80 degrees c. I don't need water cooled performance but I wouldn't mind 10-20 degrees less. Aesthetics are important and I do not want one of the giant side fan coolers. At the same time I do not want to sink $100+ into an AIO so my other option is top down air cooler.

I am looking at the Dark Rock TF and the Scythe Big Shuriken 3. I am unsure which performs better or what else is out there that is worth it. What would you recommend?

From what ive read the noctua chromax L9i/a are the best combination of cooling, noise and looks for a low profile cooler.

I recommend the Scythe as the best value. Its significantly less money than Dark Rock TF or Noctua C14. Will give you solid performance. Scythe stuff is great quality.
t
If you'd like something a little bigger, but not a whole lot more money, look at the Shadow Rock TF2. Its a 135mm fan (and larger heastink to go with it) Vs. the Big Shuriken's 120mm setup.

Really depends on what case, motherboard and RAM you have .. as well as how your case airflow is setup. Tower coolers (ones with side fans) almost always cool much better thean flat coolers. Reason is unless case has an vent with intake fan directly above cooler the air being used by by cooler is 8-12c hotter than room (tower coolers have 2-4c warmer air). Poor case airflow while gaming these air temps can be as high as 25-30c hotter than room. Reason is fan pushes air down through flat cooler hitting motherboard and turning out, hitting RAM, GPU, etc. turning up along side of cooler and fan where it is drawn right back into cooler. Tower coolers normally draw air in from front side of case and exhaust their heated air directly in front of case's rear exhaust vent. But even with tower cooler case needs to have good airflow and supply cooler with cool air.

Airflow is importnat. But, in my experience, the reason top down coolers have less relative cooling potential, is because they usually have smaller heatsinks. Tower designs are much easier to design with a relatively larger heatsink. That said, top down are absolutely fine, until you use a CPU which saturates the size of your heatsink.

I just bought a shurikan it comes in tomorrow if I remember and have the time I'll put some numbers down here
I need to redo and move my top fans but I'm returning the shuriken as it performs no better than the stock amd 3600 cooler.

Maybe user error but i was definitely expecting 10-15 degrees cooler and I'm not getting that.

Hmm. I would try installing it again to double check. Your stock cooler is the Wraith Stealth, right? The heatsink on that is definitely smaller than the Big Shuriken 3. And the Shuriken should at least be quieter, for the same temps. Because the Wraith Stealth is 2500rpm.

Alternatively, I suppose you could try to get one of the coolers which ships with a 3900x

God I hope I get better results than that. I have the 3600 and was hoping for some significant improvements over the tiny little stealth. I heard that the spire is very close the same temps as many Low Profile but The stealth seemed very anemic

Don't judge the Ryzen cooler performance by temperature alone. Also look at the clocks. Better cooler you have the higher Ryzen boosts, which again increases temperature.

That said I am not particularly happy with my Noctua C14S either. The hotspot spikes to 80C way too quickly for my tastes. 🤔

That's your opinion and you are entitled to it. But based on your reply I suspect your experience is quite limited. My knowledge is based not just on my own but others who like me have years ofexperience testing and reviewing case airflow and coolers, both tower and flat / pancake coolers in many different case designs. Everyone who has monitored air temp into coolers has found flat coolers to lag behind tower cooler performance. Only time they come close is like I said, when case venting is directly above / beside CPU cooler.

Air coolers under heavy load react almost 1:1 to air temp changes into cooler. If air is 5c warmer, than CPU will also be 5c hotter .. so supplying air coolers with air close to same temp as room is very important. As I said before most cases have almost wothless fans and even those good fans rarely are setup so they flow cool air to component coolers as needed.

Yeah and the point of my post is that you have to look at things in relative comparison. Most top down coolers have less heatsink materal and/or surface area, than similarly priced tower coolers. You can't really do a mostly fair comparison. Most top down coolers are smaller, therefore less capable, as a rule. I have plenty of experience.

You would have to make some very specific choices, to actually get a top down cooler and a tower cooler, which had the same fan size and also similar enough heat sink size, and also similar overall quality (and that's ignoring pricing). And when you do find those top down coolers, their performance is as good/nearly as good as quality tower coolers. But they can demand a price premium and if you want top performance, you lose much of the height advantage and therefore compatibility, with smaller cases. And that's because top performance demands a larger heatsink. The Dark Rock TF cools just fine. Similar to some of the best coolers. But its also very expensive. And its very large, more like the popular tower coolers. Its probably the only top down cooler which really is comparable in heatsink size, to the popular tower coolers.

Airflow is always a consideration, for any cooler. I don't believe top down coolers are any more susceptible to the issue (I certainly haven't experienced it and I also haven't seen compelling evidence proving it). You may run into some issues with very specific case designs. But If we are going to talk about case design...well, there's a whole market for low profile top down coolers, which can fit into cases in which a tower could never go. And I've also found that a good case is a good case. A good case shouldn't demand a specific cooler. Aside from form factor specific sizing issues.

I'm in the exact same mode with my new 3600, except I am building in a mATX/ITX case with a max cooler hieght of 150mm.

Search Engine: "Review [insert CPU cooler name]"

That being said, why not just go with the AMD Wraith Prism:

615uW1DbLVL._SL1500_.jpg

They can be a little loud and that's why I'm not going with it. Also, they do cool decently, but not excellently.

The best top down cooler for actual cooling that I have researched so far is:

81SPOa8QnuL._SL1500_.jpg
This is essentially a full 140mm tower cooler flipped n its side. The problem? 70.00USD --Not just no, but no fuck no.
Noctua NH-C14s

Bottom line here getting cool air to top down coolers is much more critical than it is to tower coolers. Top down cooler are harder to keep cooler's heated exhaust separate and not mixing with cooler's cool intake air supply than tower coolers. I've tested it, and others have tested it. Below is data from testing Thermalright AXP-100 (6x 6mm heatpipe 120mm fan cooler with similar performance to 4x-6x 6mm heatpipe 120mm fanned tower coolers).

Found I get lower temperature using TY-100 pulling out of AXP-100 than pushing in so I did some runs to see. Ends up it's the air blowing down into cooler that is much cooler. Air blowing down through AXP-100 hitts motherboard and goes out hitting the GPU, RAM, I/O housings, etc and comes back up around cooler and is sucked back in by fan. With fan pulling air out of AXP-100 goes up and away. Hopefully your case has a vent and/or fan that catches it and removes it from case. CPU is 5-7c cooler with fan pulling out of cooler.

Running TY-100 pushing in again and finding the heat difference is because of air temperature over cooler / fan intake. Idling at 2400rpm the air 30mm above AXP-100 is 28.5c with 22c ambient. That's with a TY-140 40cm away and 15cm above work top blowing 22c ambient over test setup.

From now own I'm going to worry more about what actual cooler intake temperature is than ambient temperature. rolleyes.gif

Link to long thread about AXP-100 and links to other testing below:
https://hardforum.com/threads/thermalright-axp-100.1732322/

Testing done on GA-EX58-UD3R Rev 1.6 motherboard setting on a bench with GeiL Value Plus RAM and old Radeon X1600 Pro GPU. It's the GPU, RAM, I/O fittings and other chips/pots on motherboard turning the airflow coming out from under AXP-100 up, than intake fan on cooler pulling it back into cooler. I suspect mostly the RAM and GPU but it all adds up to much warmer air going into cooler.

When fan is sucking air up through cooler it just keep going up into room.

I don't think any test setup running a downflow cooler can get room ambient air to cooler. Top or bottom. With upflow air going to bottom is being warmed some by motherboard components. With downflow air coming up off of motherboard is mixing and warming up intake air. Well, could if you put a barrier between intake and air coming off of motherboard... a 1 meter funnel leaning off to the side to get ambient air. :D

Tower coolers are not as problematic because air flows in over RAM and out over motherboard I/O so no mixing to worry about.


So like I posted above. From now on I'm going to monitor cooler intake and not room temperature. ;)

There are many top down coolers with as many heatpipes and equal cooling ability that cool very similar to tower coolers when they are using air the same temp as tower coolers. Problem is top down coolers by design are much more likey (like almost always) to end up mixing their heated exhaust air with cool air coming to them .. and thus end up giving higher CPU temps. Not because they can't cool as well, but because the air temp into them is several degrees warmer than it is into tower coolers. Anyone who has accurately tested coolers knows there is an almost exactly 1:1 ratio between air temp into cooler and resulting CPU temp as same fan speed and CPU load .. if air into top down cooler is 5c warmer than into comparable tower cooler, then CPU temp will be 5c higher too.

Again, bottom line is not top down quality or ability to cool, it is air temp entering top down cooler is almost always several degrees warmer than into tower cooler .. and it's much easier to keep coolers' heated exhaust air from warming up airflow into cooler with a tower cooler than it is with a top down cooler.

Form what I have read, the Scythe Big Shuriken 3 performs poorly given its size.

Anyone who has accurately tested coolers knows there is an almost exactly 1:1 ratio between air temp into cooler and resulting CPU temp as same fan speed and CPU load .. if air into top down cooler is 5c warmer than into comparable tower cooler, then CPU temp will be 5c higher too.

Again, bottom line is not top down quality or ability to cool, it is air temp entering top down cooler is almost always several degrees warmer than into tower cooler .. and it's much easier to keep coolers' heated exhaust air from warming up airflow into cooler with a tower cooler than it is with a top down cooler.
" CPU is 5-7c cooler with fan pulling out of cooler. " Did you measure your VRM temps when the air was blowing down on them vs atower cooler that has virtually no air flow over the VRMs? Ithink you can overcome the hot air getting pulled back into teh cooler by using better case ventilation. My current case (not the one I am building in) has a 230mm fan on the side door blowing directly into the MB/Video card area.
IMO, the price that Thermalright wants, at 80 bucks, is ridiculous.

Well, to be fair this discussion was not about this specific top down cooler. AXP-100 just happened to be one I had data showing how much higher temps were with fan pushing toward motherboard vs pulling air out. All caused by lack of heated exhaust and cool intake airflows. Keep in mid those tests were also done on an open bench test station with TY-140 fan flowing air over it, not in a much worse and hotter case environment. Besides, that $80 model is the all copper 'show-off' model, not normal one that sells for less thant $40 in EU before tax.

Having side fans usually causes hotter rather than cooler air entering coolers. All 180-230mm fans I've tried have been terrible performers .. often a good single 140mm fan will keep system cooler than the big ones do.

Alpenfohn Brocken EVO will fit and is good performer too, if you can find one.

There are other quite good 90mm and 120mm fanned tower cooler under 150mm tall, but I can't think of them off the top of my head because I almost always build in cases with 160+mm CPU clearance. Could you post a couple of links to sites you can buy from.

I'm doing that research now.
