Whats known as the best air CPU cooler?

Take a deep breath Helios. relax, set down and have a pint on me. NoFan isn't worth getting upset over. LOL

Haha, didn't mean to sound like that.

. Just pointing out that you don't need a cooler that is designed to be passive to passively cool a CPU. Others can do it as well

Whats the point of making the cpu cooler passive but then having to increase the case airflow? just use low rpm quiet fans all around.

Agreed really, a well balanced system with low RPM fans all round is better than having case fans to compensate for cooler or vice versa.

I couldn't help myself.

I think optimizing a system's airflow is the single most important part of build a computer.. and sadly it is the most miss-understood and neglected.

NoFan CR-95C is a monster. It is only 148mm tall BUT is 180mm in diameter with base offset to give PCI-E clearance, RAM must be less than 32mm tall, is only 4 single ended heat pipes that transfer heat into 160 "ice pipes" and doesn't cool any better than stock cooler. It is silent, but the rest of our "normal" systems are not, so what's the point?

I can say from a year of use that it's wonderful.

FT02 is great case for passive cooling. Looks like system is passive except for Geforce 780Ti. Isn't it kinda loud?

If you go for the Be Quiet Dark Rock pro 3 (which I have), be prepared with a team of cheerleaders, some alcohol (copious amounts) a Macguyver type mentality, and a belief that your board wont snap in two as you attempt to install it. As fitting it to a standard board was I found, most challenging. Worth it in the end though (three hours...), very quiet, and keeps my Haswell well below 80c max under all tests other than IBT.

Correct.

It's noticeable, even at idle. I'd love a totally passive 780Ti.

Years back I had a Gigabyte Radeon HD 5770 Silent-Cell and loved it.

Couple years back Colorful showed a passive prototype; "Colorful GTX 680 iGame"
http://www.vortez.net/news_story/colorful_float_a_passive_gtx_680.html

Little to colorful for me, but looked interesting.

I wrote to them about it - I wanted one - and they replied that it was not available:

we have not import the KUDAN series to Europe for private user, only
projects for system integration with industrial background.
The KUDAN after sales service for private user is to complicate and
expensive.

That passive 680 is pointless IMO. It would never work with no case airflow at all, which defeats the point of it being passive as it would need fans elsewhere!

Yeah, I knew their retail sales isn't in western countries. At least they replied and explained.

In a case like SilverStone's patented motherboard turned 90 degrees so airflow is from bottom to top it can be done.

HD 5770 TDP was 108w and the Gigabyte Silent Cell worked very well in a conventional front to back case with 1 bottom and 1 top 140mm vent.

Any baseline or air intake temps for these results doyll?

What are you talking about? I have none of my testing posted in this tread.
Or are you just trolling because I keep pointing out the serious problem with your TIM testing not having a monitored baseline?

I assume you are in some position at OcUK. As such I would think you would want the integrity of OcUK to be exemplary based on credibility and accuracy. Yet you keep your TIM review with no baseline temperature at the top of OcUK Air Cooling forum.

You know, I see a post on the first page with you saying "any errors let me know", and you seem to rate the test otherwise you wouldn't have posted it, yet I don't see an ambient temperature or air intake temperature etc or even if the same paste was used with the various coolers.

They are the same results per this recent post? - http://forums.overclockers.co.uk/showpost.php?p=28009731&postcount=3

It's easy to rip apart results as I have just done so and you would be wise to remember this in the future. And no I do not have a position at OcUK and I never place the thread there.

All of the information you are seeking is on thelab.gr website and can be accessed with the web address at the bottom of the chart.

I have no desire "to rip apart results" as you put it. You are not trying to verify the integraty of TheLab data I posted, but instead are trying to "stir the pot." Pointing out that a series of tests do not have the needed criteria used to be able to compare them is not an attempt "to rip apart results." It is only stating the facts about your TIM testing.

I know you put a lot of time and effort into your TIM review, but the simple fact remains. The temperature reading mean very little when there is no baseline being monitored. There is an ending point CPU temp under stress), but without the starting point (what the air temperature is in room or even better going into cooler) there is no way of knowing how one TIM CPU temp compares to another.

If you are really interested in knowing what TheLab GR testing criteria is and can't tranlate it like most of us do with google translate or similar, let me know and I will post it for you.

Its just that I do not see any ambient temp shown on the data so those figures are meaningless to me or indeed "air intake temp" in fact I can think off more questions about it if I really tried. It also says "edited by doyll" in the corner of the picture? so are they not your results?

Bit off topic guys, if testing TIM, all are so close its not worth bothering about a few c in ambient temps. Now if its cool labs liquid metal, this stuff is in a whole different league. 5c better than big standard pates. But a nightmare to remove from a cpu ihs. I love it but haven't used it in my 4790k as I don't have access to an isopropyl jet wash. My chip is hot when gaming, and if I used clu/pro I know I could get it a bit lower.

stulid · 8 May 2015 at 00:19

The coollaboratory stuff is indeed a bitch to remove and "etches" the surfaces.

Worst is copper, might as well just wet+dry it to remove that pastes mess.

I used it on a 4770k, 5c better than mx4 or chill factor, both of which I rate highly. Sold that cpu on MM to moogleys who put it through a jet wash to clean it up. Just use mx4 on the one in sig. My second 4790k, not a golden chip tbh stulid. OEM version so warranty is up soon so might scalp it and put some clu on the die. I did have to sand the base if my k2 cooler though after using liquid metal, 2000 grit paper which is more like a polishing cloth tbh.

As I said, all testing was done by TheLab.gr. Editing a chart has nothing to do with the testing. I 'edited' the chart to make it easier to read than the original. The data is only copied from their chart layout to the my chart layout.

As you do not seem to understand what Delta temps are I will explain. “Delta T” is the most common use of the word delta. It is the difference between the air temperature going into case or better still the CPU cooler and the temperature of CPU. If you have the delta temperature, you do not need to know what the air temperature was. You cannot calculate a delta temperature without having both CPU temperature and air temperature at the time CPU temperature was taken. It simply subtracting the air temperature from the CPU temperature. If a chart has the delta temp, there is no need for the actual CPU temp and cooler intake air temp. But if chart does no have the delta temp, we need both the CPU temp and the intake air temp.

Your testing only has the CPU temperature, but no reference temperature at the time CPU temperature was taken so no way of knowing if the TIM was 1c or 2c different in ability to transfer heat .. or if it was a difference in the air temperature at time of test.

stulid · 8 May 2015 at 01:11

Ive looked at that lab group test and not convinced by it.

"Cooler intake air temp" is not something i see listed either? There doesn't seem to be anything mentioned with how its setup? Translation is flaky
