DeepCool Announces GamerStorm Assassin II CPU Cooler

DeepCool rolled out the second generation of its GamerStorm Assassin type-D twin-stack CPU cooler. The Assassin II is huge, measuring in at 143 mm x 158 mm x 167 mm (WxDxH), weighing 1.48 kg (including fans). Its design consists of a large nickel-plated copper base, from which eight nicke-plated copper heat pipes pass through, conveying heat to two aluminium fin stacks. The two stacks are not of the same shape.

One of the two fin stacks features an edge that's pointing towards the rear of your case, and hence you can't strap three fans onto this heatsink, just a push fan, and a conveyor between the two fin-stacks, but not a pull fan. The push fan is a 120 mm spinner, running between 300 and 1,400 RPM, pushing up to 68.06 CFM of air, with a noise output ranging between 17.8 to 27.3 dBA. The conveyor fan is a 140 mm spinner, clocking 300 to 1,200 RPM, pushing up to 70.08 CFM of air, with a noise output ranging between 17.8 and 27.3 dBA. The Assassin II can handle all modern CPU socket types, including LGA2011v3, LGA1150, AM3+, and FM2+. DeepCool didn't mention if the cooler is good enough for 220W TDP chips such as the AMD FX-9000 series.

looks nice but too bad you cant put the 3rd fan on that and i dunno how far that tail would improve the cooler performance

I dont know how they test tdp for air coolers but it seems weird or false to me. AMD says to use liquid cooling for the 9590 and well I dont think they air joking. seems air cooler companies have little to no expertise when they throw in ratings that air against what a company says that has real thermal specialists.

AMD recommends a 120mm CLC those are often inferior in performance compared to high end air coolers like this one. Most dual tower air coolers can handle 230W TDPs at 1500RPM and if you stick 3K RPM fans on them they can even handle 300+W TDPs.

I remember the mods on another forum posting the recommendation from AMD and it had no real specifics but that also brings me to that the thermals for Intel and AMD are very different and air cooler companies never include that information.
they probably just use Intel throttle temps and call it a day.
300w+:eek:we better call MSI and have them get the nitrogen ready.

we all know Devils Canyon is up to 5ghz on air too and neither pull the kind of wattage cpu air cooler companies put on a box.

edit-would def like to know if I am missing something

Sure looks bulky for an "assassin". :D I suppose it makes up in performance.

No AMD does NOT say you must use a liquid cooler for the FX-9xxx series CPUs. AMD offers a kit with liquid cooling but the top HSFs cool the FX-9xxx series just fine. If you actually compare liquid cooler performance to top line HSF tower coolers, you will see that the top HSFs are in fact superior to most of the CLC/AIO liquid coolers. In addition HSFs never leak coolant like the AIO/CLC liquid coolers have been documented to do, causing considerable and expensive PC hardware damage.

As far as HSF or liquid cooler performance, it's best to use reputable online sources such as Frosty Tech, Hardware Secrets, etc. who actually know how to properly test a HSF/liquid cooler and do so. There are many variables with CPU coolers and if these are not controlled in a test, the data is meaningless. CPU cooler companies may or may not be properly reporting the real world cooling performance of their coolers.

There are numerous top of the line tower HSFs that will properly cool an FX-9590 or any other X86 style CPU. Below is an example of some of the "top 5+" HSFs that have actually been used with excellent result on the FX-9xxx series CPUs. I have personally conducted extensive, as in 20+ hour Prime 95 stress tests on the FX-8xxx series CPUs OC'd to 4.7 Ghz. (the base clock of the FX-9590), with the Xigmatek Aegir SD128264 HSF and it keeps the CPU under 61C as AMD specifies - even in these marathon P95 torture tests.

Don't be duped into believing AIO/CLC liquid coolers are better. Do your homework so you know exactly what you are getting. People often do not understand just how inferior these CLC/AIO liquid coolers are until they see the cooler performance data. The Corsair H60 is a perfect example and a popular mistake that many people purchase. There are over a hundred better performing HSFs than the H60 liquid cooler and many costs less than the H60 and never leak coolant to damage your PC. In addition to the inferior performance of the H60 compared to a 100+ HSFs, there are serious reliability issues with these coolers. Check the Corsair website for the sad tales of woe from those who have purchased these coolers and had multiple failures.

BTW, this new Assassin II is probably a great cooler but larger than it probably needs to be. It would be nice to know exactly how large a fin area is really effective. This takes a lot of carefully controlled testing to determine but it is worth the effort, IMO.

the cooler bundled with the 9590 often times is the h100i and is not bad..
4.7ghz is not 5ghz and your vcore is probably lower than the 9590 out of box
you linked tests for 125w
its 62c for safe daily temp for good lifespan and up to 70c according to overdrive
5ghz can be stable on air with the best of the best case fans and heatsinks but is AMD just going to trust everyone and not issue a recommendation.. yeah that would be dumb if they didnt

that is it? someone says liquid coolers are crap and gg?

is what it is I guess.. wasnt trying to start a fiasco but if that is all there is to be said then most tdp ratings are garage..

where did you ever get 300+ from anyway? dont bother I guess..

Umm, NO, but like you said, that is your opinion, not a fact!
Typical BS from an airhead fanboy.

The NH-D15 is 4C behind the best water cooler that crazyeyesreaper reviewed and it's using 1500RPM fans. The Swiftech H240X/H220X uses 1800RPM fans the corsair H105 which is only 3C better than the NH-D15 and uses 2500RPM fans. If you put 2000RPM fans on the NH-D15 it'll beat the H105 and H240X and still cost less. So while an out of the box air cooler won't beat a CLC if you put 2K RPM fans on dual tower air coolers they will win.

Objectively, the Noctua NH-D15 is better than most watercooling solutions. It is an undeniable fact.

no doubt the d15 is great but nothing compares to custom loops and aio do have advantages like being able to have lower temps than ambient.

there is also that with air coolers your relying on case fans to pull the hot air out of the case.

I dont think there is really any denying that air cooling is not what you want for high overclocks and high tdp.

with gpu's your talking dramatic differences if you switch out a air cooler for a block or even a cheaper aio.

Physically, it is impossible for any AIO watercooling solution to get your CPU temps bellow ambient. The air that cools your radiator, being ambient, is the absolute lowest. And that is, if your TDP is exactly 0W

hm.. I thought they could just like custom loops.. will have to check it out further

my point was really just that high tdp ratings make no since.. Intel has lower tdp for 5ghz yet that is all that can happen with air cooling.

No loops can. As long as you don't have an active cooler (such as gas powered) it just cannot go below ambient. That's a very basic physical fact.

And yeah, you can pretty much max out many CPUs using air cooling. That is, if the thermal interface is not utterly horrible.

That expert enthusiastic thing is to use sub-ambient matirials such as cascade, dry ice, liquid nitrogen, liquid helium, gas-cooled water, phase-change and such. just by water and fans that cool it using ambient air sub-ambient temperatures will never be achieved

Any1 catch what size the heatpipes are, 6mm or 8mm?

Probably does something to vortices and laminar flow, but what do i know? I'm a stooge. :twitch:

Not impossible believe it or not. See below.

The difference between max OCs of air/H2o is marginal, perhaps 4-500Mhz at best IME. The benefit, IMO, to using H2o is that it can extend the longevity/duration of the chip/OC due to lower overal temps, which generally allows one to use lower Vcore (in the case of CPUs)

yeah idk anymore.. I just use air cooling and havnt gone further. the most I really look into it is what they do at computex and air is always the lowest clocks.
guess your right seeing as how some motherboards are made an even incorporate using a ln2 pot.

Below what? i could believe it, and i could not believe it. Science fact is that using only water through metal, and using ambient air to cool it, its either you at ambient or above it. There are no other options.

Having this discussions feels like having a discussion about whether is helium really lighter than air or not. It's inarguable. Using Chemical reactions to actions (the bong) is not what we're talking about here.
