AIR vs AIO. 18c drop in temps

The new arctic liquid freezer II coolers 250 & 280 cheaper than the D15 while the 360 is the same price.

240mm AIO quieter and cooler than a D15

Thanks for sharing this. Good to see a 9900k being used. Since it's easy to copy their settings, I wanted to replicate their testing and share some more data points.

I ran their exact settings with AIDA cpu/fpu/cache for 15. At 10mins, I reset the hwinfo64 sensors so I'd have a clear idea of what an average load looks like over time.

So while there is the occasional spike, on general it's a relatively mild load. Keep in my I'm in a case next to a radiator so my ambient will be high when doing a like for like. The highlighted fields are the important ones to pay attention to. Overall, you'd mentioned about 150amps but you can see now that it's easy to spike upto that. I wouldn't consider Kitguru's setting extreme by any stretch. These are just 9900k things.
 
@Ross Thomson Here is P95 non avx with the same conditions as above. Kitguru settings. 15min run and hwinfo64 reset after 10mins to get average loads

As you can see P95 is very consistent in it's load thus leading to higher average temps. This is why I like using to just to find the max thermal capacity of a cooling unit because the cooling unit doesn't get a break.
 
Last test. My daily settings. 5.1ghz all core. 1.33v turbo llc. P95 non avx. As you can you see temps are *high* This is more or less the thermal limit of this cooling setup. Again, the consistency of load from P95 is what makes it very good for stressing cooling systems.

If the day comes that an air cooler can match this, I'm all for it. Advancement is great.

Kit Guru test methodology give no details of how the testing is done. Is air temp into cooler / raidiator monitored and recorded same time as CPU temp is recorded? Are fan speeds the same for all cooler when temps are recordced? Is noise leve the same on all cooers when temps are recorded? Therfore Kit Guru testing is ambiguous and invalid. The same lack of testing methodology applies to tom'sHardware reveiw. Lots of fancy graphs without any explaination of test procedure makes them invalid, even though it's only CLCs being tested.

Even with this dubious testing at maximum OC, CLC temps range from 57.1-66.5c with D15 being 63.1c .. 3.4c better than H100 and 6c warmer than Castle 240DX. and DRP4 is 69.1c, only2.6c warmer than warmest CLC. Noise levels have DRP4 at 39.4dB, quieter than quietest CLC at 41.2dB, D15 at 44.1dB and H100 at 53.7dB. Human ear needs about 3dB change in sound pressure to register a difference in sound level, and 10dB change sounds half / twice as loud to human ear. So to our ears D15 sounds the same as quietest CLC and loudest CLC sounds almost twice as loud as D15. Compound all of this with D15 being one of if not the most expensive air cooler on the market while coolers like TRUE Spirit 140 Power cool as well as D15 at same fan speed costs about 4/7th's as much. CLCs range from £50 to £232.99 while air coolers range from about £9 to NH-D15 chromax.black £92.99, Cooler Master Wraith Ripper at £119.99 and most expensive Prolimatech Genisus w/ Silent Wings 3 PWM High Speed fans. That leaves approximately another 63 CLC's costing more than most expensive air cooler listed on OcUK.


That is your assumption. One not backed up with any unbiased testing of air coolers to verify your claim.

We need air cooler testing done with system noise level and air temp going into cooler and radiator recorded at same time CPU temp is ran on your system for us to have data that will either verify or refute your claim.

yawn. same crap different day. "dubious, assumption, blah blah blah." Best thing about this thread is it exposes your lack of direct knowledge so hopefully it's a nice warning to others.

Your "dubious, assumption, blah blah blah" is all it is without supporting data of what your system might do when setup with a good air flow and air cooler. You go from a Dark Rock 4 (which is far from being one of best air coolers) mounted in a case that was quite possibly not supplying DR4 wiht air within 5c of room ambient to a CLC and make outlandish claims of how much better your new CLC is. If you live near me you can bring your sytem over and we could set it up with good airflow and top tier cooler and see what it will or will not do. But I doubt you want to know the truth.

It's clear you avoided watching or reading any links I've posted as you did not address a single one as a point or counterpoint instead solely relying on your hypotheticals. You've done nothing to expand your knowledge base.

Every reviewer or test that doesn't conform to your narrow view has a lot to answer for in your head.

I hope you end up with a 9900k one day. Will be fun to see the mental gymnastics.
 
Making a small list of people who don't know how to setup cooling configurations according to The Last Airbender.
- Derbauer
- Buildzoid
- Kitguru
- TechYEScity
- Craftcomputing
- Optimum tech

Don't worry, I'll try to keep the list updated for you.
 
I've posted a large sum of data and reference points from my testing and that of others who are well respected. You're drunk off confirmation bias. I, nor anyone else can change that. Report away or create your own thread from legacy data points that have little relevance.
 
To show the difference between my Alphacool 360LT AIO and what a custom loop allows:

This is me running P95 NON AVX for 90mins. CURRENT IOUT is what you want to pay attention to. The limit of my cooler is around 150amps average power draw as can been seen here:

Now Let's look at a custom loop 9900k running P95 AVX. You can see the custom loop allows for another 50amps (CURRENT IOUT) worth of cooling on average under sustained high loads.

The 9900k is a pain to cool remains true :)
 
Thanks purely to cold weather and offset voltage:

Basically if you can drop your ambient and start at a lower temp, that benefit extends to lowering your peaks thus giving you more headroom. In this case, my starting temp was 19c thus I was afforded the extra headroom. This is a "winter" config. Actual gaming and general usage temps are obviously a lot lower than this quick P95 run. Referencing earlier results, a drop if 5-7c nets me another 12amps average of heat output which is what I'd expect.

Case temps do play a role so having two graphics cards in the case is going to be detrimental to the temps using an air cooler. Problem with reviews they use open air benches so when you actually come to use in a case the temp is going to be worse. This is unlike an AIO that should be using air from the outside.

Yeah but I can see why they test it that way to control the variables and not having to update their test environment over time.

Even then this toms review of the KS shows a good like for like using 3 tiers of cooling: https://www.tomshardware.com/uk/reviews/intel-core-i9-9900ks-special-edition-review

You can see that under a decent load the D15S hits tjmax and starts dropping frequency. Expand that to a more stressful load and that tjmax will just be hit faster while there’s more overhead to be had with the AIO.

Custom loop naturally being even better.
