I stumbled on a great cpu air cooler. Big size

[philipma1957]

The Zalman Fx70 Fanless CPU

http://www.newegg.com/Product/Product.aspx?Item=13C-0007-00002

first off it is massive really big.
It comes with a set of fan brackets.

you can put a 120 mm fan on it.

I just did a 100% cpu stress test on my new z170 build.

With a cheap pwm fan from coolink

Swif2 fan 120p

http://www.coolink-europe.com/en/categories/23_29.html

and the i5 6600k at stock speeds My temps across 4 cores are 22c

at idle 10c

the zalman is freaking huge. but with rebate it was 39 bucks.

I am using:
a Corsair carbide 330r case
a gigabyte ga-z170x-gaming 7 mobo
2 x HyperX Fury 8gb sticks ddr4 2133
windows 10 home
a 2tb samsung ssd
the intel gpu for the time being
rosewill fanless psu
1 stock fan from the carbide case set low.
i5-6600k at stock


The zalman fits in the carbide case with the exhaust corsair fan removed, more to clear the mobo. It has a white built in cover that is too high.
So with no room for the exhaust fan I decided to add the optional 120 pwm fan to the cooler.

I will post some screen shots of this as I expect this to be a great over clocking air cooling system for the i5 6600k

what are your ambient temps?

what are your ambient temps?

Sub 10c, obviously. Was thinking of getting one of those walk-in refrigerator rooms for my PC too.

Sounds like the monitoring software for his board isn't quite ready for Skylake.

Hey, maybe he lives in the antarctic...wait, no NJ.

Yeah, walk in freezer I guess.

yeah I considered that speedfan 4.5.1 is not accurate as 10c idle is too low.

but 100% 4 thread stress test jumps to 23c across the 4 cores.

I am willing to bet that the 12 to 14 c jump is accurate.

Show me an air cooler that does that 4 cores 100% maxxed and the cpu only jumps 13 c



plus it is not noisy and if you really just want to oc get a noctua pwm 3000 rpm.

I will do a big thread on this with photos as I find more up to date

skylake software.

This cooler reminds me of the prolimatech pro-mk-26-nk gpu cooler



http://www.newegg.com/Product/Product.aspx?Item=N82E16835242041

you can't get a hd7970 to go over 55-65 c no matter how much you overclock.

 

[ClockHound]

Hope your enthusiasm isn't tainted by more accurate monitoring software.

Look forward to the full report.

Those numbers are incredibly wrong and shouldn't be trusted.

My apologies for making the assumption everyone would understand that my amazement was not 9c or 10c at idle and 23c for max

but that I was only able to raise the i5 6600k 13 c under a full load.

I took some real temp shots
my in house temp is 20c

realtemp under no load reads
both temp readers no load
both temp readers full load as claimed by cpu-z

so raised it from 23c to 42c and the optional fan moves 75cfm maxed
if I use a noctoa 3000 rpm pwm fan it would be better.

I will need to get a few cable extensions for my rosewill silent night psu to reach the mobo jack and the cpu jack but I am thinking I can have a very powerful 1 card over clocked cpu/gpu and it will run quietly

 

[philipma1957]

I did a 90 minute prime 95 pc is under 50c on all 4 cores

this cooler is a winner .

needs a big case and depending on how hard you want to oc the pc . I think it will

never get over 65-75 c

As little power/heat as that CPU has going on at stock clocks I would expect any halfway decent block of finned metal with some air moving in it's general area to cool it well enough. Close the case and clock that thing up if it's able and see what it does. 4500 or so oughta do it.

 

[RampantAndroid]

FWIW I did a quick test - on my 3770k using a Promlimatech Megahalems...30C is the maximum delta (in a case where the GTX980 has no fans running) - so ~20C delta isn't really surprising

 

[PhIlLy ChEeSe]

Your first screen shoot show1.56v on the CPU at default speeds?D:

 

[PhIlLy ChEeSe]

double post sorry!

this weekend is the goal to oc it .

I have to say it is really quiet. 91 minutes of prime 95 and the fans did not need to ramp to full speed.

I love how a product supposedly designed and manufactured for 'fanless' needs to accommodate a fan. live by your own sword or fail with it. Not the OP, but the product maker.

True but it is rated at 80 watts fanless.

I stumbled into this as the z170 mobo does not allow the exhaust fan to fit.

The gigabyte has a tall white shield that is ⅛ of an inch too tall to allow the cases exhaust fan to fit.

Since the cooler is 2 or 3 inches away from where the exhaust fan should be I put the optional fan on the heatsink it blows out into the spot where the exhaust fan would have.

I need to
A: get some extension cables
B: put my hd7970 with the prolimatech cooler in
C: swap the cheap pwm fan for my noctua
D: oc and test

I am thinking this will be a very quiet 1 gpu build with really good oc.

The Corsair case is nice rather then my fractal r4 case.

I will post more over the next few days.
Some sound readings with a meter etc.

the megahalems is 69 usd

the zalman is 39 after rebate

I see there is some testing on the i7 and the i5 one the front page of anandtech today they are using a water cooler at a cost of 89.
I will see how close I can get to it with my setup. My AR cost is 39+ 10 = 49

I just got the 10 usd rebate yesterday

The black one cost more - it's a heatsink that at one time (years ago) was considered one of the best and has since been forgotten. Much like the Thermalright True120.

Keep in mind, you cannot really compare your temps to a reviewer's temps - not all CPUs are the same, not all airflow setups are the same

I thought about this briefly. "you cannot really compare your temps to a reviewer's temps." True. Some number of users will have a better airflow strategy than the reviewer deploys, and many others will have one that is worse.

But a comparison review will provide relative performance among HSFs that give a good rank-ordering, unless they are "payola" reviews. For Instance, I can trust comparison reviews from HardwareSecrets, TechPowerUp, TechReport or Frosty-Tech.

The FX-70 is not likely to be a good performer under stress loads, since the FX-100 is not a good performer:

http://www.hardwaresecrets.com/zalman-fx100-cpu-cooler-review/7/

And I can confirm that the review is consistent with personal observation, since it includes the EVGA SuperClock -- later renamed the EVGA ACX. It's relative performance against the Corsair H100 in the review is consistent with other rank-orderings.

So my own question derives from lack of experience with the new Skylake and Z170 chipset. It uses 14nm lithography. The 6600K has a TDP spec of 91W, or not much different than previous generation CPUs in its class. I would guess that this means higher expected readings of the Tj sensors than with those earlier generations.

I wouldn't expect any overclocking miracles with the Zalman.

For the OP, the load temperatures at spec speeds tell enough. Load temperatures with a measure of thermal wattage tells all. Idle temperatures hardly mean squat, and the sensors are inaccurate at idle in any case.

Well I have been playing with oc for a few days. up to 4300 it work very nice.

But I go to blue screen at 4400.

Not due to temps as the cooler never allows temps over 63c even with clock 4400.

At clock 4300 I run around 59c

I am trying to figure if I have:

a poor i5 6600k
a poor mobo
a poor psu
bad settings for the 4400 and above oc


and the zalman 100 does not look much like the 70.

I am having real world issues at the moment so I will get back to this when I finally figure out why I can't run prime 95 at 4400 and above.

 

[RampantAndroid]

Have you looked at the voltage?

 

[philipma1957]

Have you looked at the voltage?

yeah I have punched in multiple numbers.

and I can run 4300 endlessly and go to blue screen at 4400 in under 20 minutes with good temps around 60-65.

I am not as familiar with oc and gigabyte.

I also think my psu could be why.

I will have more time on monday.

But if 4300 and 45-52c (depends on volts setting) is all I ever get I will live with it.

I need to spend time on gigabyte forums and ask for the settings people are using with their z170 giga boards

I have a Scythe Mugen2 in my HTPC. It's huge too and was advertised as being able to operate in fanless mode. The thing I like about that over AIO liquid coolers is that you don't have to worry about the pump or fan dying and overheating the processor.

 

[MongGrel]

Sub 10c, obviously. Was thinking of getting one of those walk-in refrigerator rooms for my PC too.

Sounds like the monitoring software for his board isn't quite ready for Skylake.

Hey, maybe he lives in the antarctic...wait, no NJ.

Yeah, walk in freezer I guess.

Obligatory True120Copper shot, just use it on the HTPC these days.

I'd thought about getting a fanless setup for the HTPC but all ready had that laying about.

Something on your numbers does seem odd.

 

[MongGrel]

My apologies for making the assumption everyone would understand that my amazement was not 9c or 10c at idle and 23c for max

but that I was only able to raise the i5 6600k 13 c under a full load.

If it's not reading idle speed right why would you think it is reading anything else correctly ?

I'm just saying you might look into that first.
