not biased just my own experience. i think that if you dont have an ls,st,gt....... you should go post in the air cooled room. my compressor is not that loud at 3 feet from me. if you want ill go get some test equipment from the lab and give you an precise decibal reading.......? man i could care less whats better ls or gt i just hate misinformation. i have clearly posted with my own exp. this is exactly why i dont post more of my own results i guess if you truly want to know which product is better go buy them both. peace and im out of this thread no good can come of it now.

Chill out a little. :toast: Just go play with your LS and don't worry about all this. :lol:

I think the fact you're missing is that he did all these pseudo-tests on the same motherboard with the same processor and the same everything else. The only thing he changed was the cooling methods. Even if the LS temperature is off by +10c... that means every other cooler is off by +10c so the comparisons are still valid. You see? :confused:

It's a Saturday... you have a great cooler... now just go have a :toast: and enjoy it. :up:

I looked at the ST and thought about picking it up. The bare kit was $710 in the US. Not a bad price really for proven performance. I picked up the LS for several reasons. One I figured it would be on par or slightly better then the mach II/ST. Second I plan on picking up an A64 and along with my Intel cpus I would have had to buy an extra cpu kit for the ST. That brought the price within $30 of each other. For the $30 I get the LCD, USB, and AL kit. The LS, frankly, is still a better deal. Second, this being my first phase change, it seemed that the mounting system of the LS was a little more user friendly. Third, I wasn't sure if I was going to feel at the end that it was worth even the money for the LS for the extra cpu speed.

Do I regret not waiting for the GT. Hardly, I already knew it would be better and frankly, considering this is my first experiment into phase change, wasn't remotely interested in spending the extra $500.

Do I care that that GT is better. No. It doesn't bother me a bit. If I really get into phase change and want to ge the best, I can buy one later and use the LS to cool my gpu or pick up a mach I or mach II and mod it. Which may be a better deal anyway.

Am I concerned about the noise. Sure and I'll find out just how bad it is when my back gets better and I can hook this monster up. But from what I've read the 35db with be a blessing compaired to the twin tornados I have runnig now.

I have to agree with megahurtz that all LS results so far I've seen (including my own) are better than the reviewers.
It took me some days to make it cool as I wanted (maybe you saw my pic few posts before) and now i'm satisfied.

Of course: It's Asetek's fault when the LS doesn't work properly instantly. No doubt about that. I'm still not sure why my results are so depent on the hose's position.
My rear fan is running at 100% so I don't hear the compressor. As it's getting warmer I'm afraid the comp might overheat as it's very hot

I'm not interested in convincing anyone the LS is the best choice at all (why should I?). But a loaded Prescott @-37c on the same MoBo the reviewer uses and high ambient temps (~27c) is something I wanted to let you know.

I really wonder why these discussions about Asetek/Nventiv, Ati/Nvidia and Intel/AMD are often so emotional. Most of are not payed by these companies.
It's alway like talking about sports :D

And as Jeff said I'll go and have some :toast: now ;)

Loaded prescott at -37 my ass :rolleyes:
Charlie ran his prescott at 4.6GHz with dryice and temps were -15c under load. So your Vapo LS can remove over twice as much heat as dryice can?

That does seem to be a bit off. Maybe the oc was lower with lower vcore.

4600+mhz at 1.9v on a Prescott is getting pretty damn hot. I doubt the one under the LS was running at the same specs.

Yeah. I second that. I doubt his prescott is even able to run 4,6G with this cooling ;)

Well, it is extremely unlikely if not impossible that mainstream desktop processors will ever disspate 200W, because such heat cannot possible be removed by conventional means. High performance ICs are a vague discription, too.

There are indications over AnandTech saying that 10 of Intel’s close partners in Taiwan have already received engineering samples of Intel Tejas microprocessors. Apparently, the chips function at only 2.80GHz and dissipate around 150W of heat

150watts @ 2.8ghz
(4ghz/2.8ghz)*150 = 214watts of heat

thats assuming no voltage increases. so yes i do believe we will have processors dissipating 200watts of heat.

According to The Inquirer, the CPU will be called the Pentium 5, will operate at between 5 and 7GHz, and will have 2 MB of L2 cache

Seems unlikely considering FUGGER had to use a cascade to bench at 4.7G. But you never know he could have a better clocking chip.

Lol no it was a Prescott at default Speed and Voltage (due to droopmod something like 1,42V)
The prescott is able to run ~4,4ghz@1,65V for SuperPi only. I'll try to load this voltage later

Give us a comparative reading at 4.016/1.65v

Also I don't believe even Teja's processors will be release until the work heat output is down considerably. If we see 150w released I'll be very suprised, maybe in two or three years, but they will have better coolers then too!

No. Definately not. FUGGER always gets the best chips from intel ;) :D

How have you changed the hose position to improve results?

I installed everything in the PC60 on the LS case. The hose is a bit to long and so it doesn't really fit inside the case.
yesterday i tried to install the sidepanel and therefore the hose was pressed inside the case. and that made a huge temp difference. now I get ~-51c
At the moment I'm testing how to make it hold high heat loads.

Umm, am i the only one that cant see where xsky said anything about 4.6GHz? Didnt he say "loaded Prescott" by not name a speed? Jumping to conclusions here?:confused:

I swapped my 3.4C to the 2.8 Prescott and here are my results. I cannot get this chip any faster then 275FSB. Here are the temps and Prime95 running as in the previous tests for comparision.

Very nice, have you tried increasing the vcore to get a higher oc?

Yep,

I can boot to 292FSB, but I cannot get windows to load. I tried every value in the BIOS for the VCORE.:confused: Maybe that is all the chip has? ? ?

Maybe it's APIC???

Never tried a presscott, but it does seem like you have maxed out that particular chip.

Will the LS work with a K7? Right now I am leaning towards the MachII ST, but the mounting kits can get rather expensive.

Could you run that Prescott @3.8 with 1.55 vcore for one Prime session? I am curious about the temps @ 150W heat dissipation.
