Vapochill LS and Mach ST/GT test part1

You are absolutely right about focusing on your own products. Did you actually read your own post ? ;) Im not focusing at your product at all. Im talking about a compressor from the company I used to work for.

Yes the BD35F has a more modern design, with more powerful bearings, valve system as its bigger brothers, why it will sustain the higher pressure. This is also why we dont supply the BD50F compressor with R404a, as it will not tolerate it in the lengthy run.

Also you cannot just compare a 8.5 and a 11cm3 compressor. As you will be told if talking to Danfoss, the CLX series are much more energy effecient.

I cannot or will not try to predict the failure rate of the NL11F compressor used with R404a. All I can say is, that there is a reason why Danfoss do not release it for use with R404a. That reason is, that a NL11F compressor with R404a will not last. Maybe it will will for 5 years, maybe not...

Fine lets stay away from the guessing. We have good reasons to believe CPUs to reach 200W within a recent amount of time, and we have optimized our cooling systems accordingly. You dont trust this, which is fine with me. We have different views on this - no problem.

I have beers in the fridge :toast:

If CPU's will be hitting 200W within a recent amount of time then those are going to be some rather oversize retail boxes ;)

See you could have just said that :D :)

my PM box is open for suggestions on when to consume some danish brewings :)

petervandamned,

Here are my results on the Vapochill LS w/ the Intel 3.4C also. I am running much cooler then you though.

I can use this chip w/ HT are 245 and w/o HT at 250FSB.

Is that under load? :confused:

thx a lot! great review vandamned!

Hawk, I dont see Prime95 running there :D

edit: a difference of only 7C between evap and CPU die temp would suggest a non-loaded temp too..

Yes, also, why on you LS status page are your Fans showing 12Vdc? Mine is showing me 3.6Vdc. Are you running a 220V unit?

He is in Europe so yes he is running 220V

At my test i used the same main board and the same cpu.
Ofcourse there will be other results. On my home made cooling unit I get also better results ;) Thats why i will place part 2 ASAP this will be done by a special test bank.

Hopefully i will have some more PhCh units to compare.

Thats what i was getting at, hawk you say yes it is but what kind of load? run small fft's :stick:

Here is Prime running continous. . .

The smaller FFT's he was running (8K/10K) stress the CPU more the 1024k's stress the memory/fsb more. Like i said try running small FFT's :rolleyes:

You saying there is only 4C difference between CPU Die temp and evap temp (the difference between Heatspreader temp and die temp is more than that..)?
Either one of those readings is totally way off. I'm guessing CPU temp reading - or then the CPU was not properly loaded :D

Give me a few minutes. I'll run the smaller FFT's. . .

Like macci said they still look out but small FFT's woulkd be better as that was what petervandamned was running for 10mins.

Also cpu-z says 1.568vcore and mbm 1.65 vcore
Also cpu usage 0%???

Also ASUS mainboards shows 7-9c lower temps:)

cool, at least i now know the LS is better than the stock mach2

i always thought the GT would be better and it is.

hey petervandammed, you should disable the LCD on the LS, it'll reach lowever evaps that way.

Here is w/ small FFT's.

damn my prediction was right, I knew the GT was going to be around -10°C better than the LS :)

2) Use a big MAC DADDY compressor filled with r507.
3) Keep everything else the same because the LS is much more refined than Nventiv product.
4) Price this NEW LS-XL the same as Nventiv GT...
5) Beat their temps... with today's hardware. 150mHz difference is HUGE! The enthusiast is just going to buy a "old" Mach 2 and charge with 507... or an ST for that matter! For Asetek to prosper they need a top-end model that is TRULY the best. Now don't take this the wrong way... I think Nventiv products look a bit rough, even garage-built. The LS is quite well put together, but doesn't offer the same "ooommpphhh". I believe the LS was an outstanding "first salvo" into this battle, but it's time to bring out the big guns, Asetek.

2) Both the FR8.5CLX (230V) and the NF5.5CLX (115V) has bigger brothers. However we think the LS has plenty of power. If lower temperatures is wanted, simply reduce the charge of refrigerant, and optimize for 200W.


4) We dont see the market for 1400$ cooling solutions big enough to pursue.

5) Let us await more reviews. Our experience do not show a 150MHz difference. There are huge differences between the LS and the ST, both with regard to performance and features. We will await the situation. Nothing indicates a need for even bigger compressors. If we release a bigger compressor, what do you think the next move will be from the competition? End of the day we end up in a dual scroll compressor setup, affordable for 10 people in here :)

Since Asetek claims the LS functions better with higher heatloads, let me make a suggestion:
When I ran my Prescott 3.0E to 4609, the Dry Ice was sublimating as fast as I could add it to the tube. At 1.9V, the Prescott is a veritable inferno. SOOO, replace cool running 3.4C with a Pressie and see what happens :D Now THAT'S a torture test!!!!!!!

C

well from someone who's never used phase changing i'm leaning towards the ls. the nicer looking cabinet and lcd is more important to me than slightly lower temps. and of course, the much lower price helps a lot too. that's why im saving up to get it.

if the slightly lower temps mattered that much to me i'd rather have built a custom cooler insteading of coughing up a fortune for the gt, but that's just me.

Mmmmmm....dual scrolls, mmmmmmmm.
I do like your idea about degassing to tune for 200w, though.
