But if you go read any overclocking forum you'll see that it's not heat that limits how far you can go in most cases. Getting 10c less on the CPU core doesn't gurantee you'll hit 4Ghz because the CPU may still error out. It's luck more than anything else.

the idea is to blow both 120mm fans the same way blowing across the hs and then the other fans blows it further to an exhaust such as the case exhaust or the psu exhaust

its just like have a scythe ninja in your case. big size. if you can deal with that and its maintenance free and cools your temps better wheres the problem.

if you use it with Coollaboratory Liquid Pro to knock the temp down further then....

my noctual and 2x120mm fans cost me the same price as the titan

if i wanted decent watercooling it cost me 400$ the titan will suffice for 100$

noctua nh-u12 with 2x120mm fans will beat big typhoon and ultra 120

There have been reviews of the Ultra-120 that show it beating the Noctua. Give my Ultra-120 2 fans doing the push+pull method and it'll cool better than your Noctua doing the same. I run 1 fan because I don't need anything more. It is effecient enough. If your noctua needs 2 fans to cool you CPU it's not an effective HSF.

Where are you getting that from?
The Vanessa L-Type that it was compared against generally performs within a degree or two of the XP90c cooler, and the Amanda completely obliterates the L-Type. I don't know of any air cooling that puts the XP90c to shame. Beats it, yes, but not badly.

From the review in the OP and the PSU calculator.

I tried out a few peltier coolers back in the day. They always died on me after a few months, and I smoked a system once. The peltiers only cost $15. Hopefully this is a better design. Peltiers produce a lot of heat, so you really need a design that pumps all the heat out of the case. This one does look pretty nice, especially the review where they maxed out the voltage on the cpu.

You missed the point completely. To have more VCore, the CPU needs better cooling.

Core Temp tell me I'm near 59C under load, so in theory I cannot put more juice or
increase the clock without breaching the Intel specified temperature limit (61.C)

If this cooler lower the temperatures 10C, I can try that. Sure, nobody can tell if a CPU will overclock further, but this a needed condition - perhaps just not sufficient.

i disagree. all conroes are capable of 4gig. luck doesnt come into it unless you got a golden cpu.

if you cant get there its usually because of heat. if you got good hardware ie. good memory capable of 1000, good board like the p5b deluxe and good quality high enough wattage psu which most have now. then the only obstacle left is heat on the mobo cpu and ram. as soon as i run 1.5+ the temp shoots upto 55+. its just a case of supplying high enough voltages which you are limited on most hsfs. so it calls for something special if you dont want to use water cooling which i dont. my nb is being cooled sufficently so the wall is the cpu heat. its ok to run your cpu at 1.6 volts if you can cool it so good.

so this is the next best thing reading the reviews.

the noctua is doing the push and pull it cools it further with 2 fans compared to 1. so sure its efficient just more so. plus i run my fans low speed for quietness.

it sounds like most are content at 3.2, 3.4 speed and dont like heavy big hsf, wires or its the wrong colour.

how can it be expensive if beats all air coolers and beats some water kits

 

[Madellga]

to whom you disagree?

BTW, Xbitlabs just reviewed this cooler and they are not impressed. In their test, it's just a bit better than the Typhoon, not worth the delta price.

Increaseing the voltage will fry the CPU even if the temperatures are kept low. It's becoming more of a problem with recent generation CPUs than it was in the old AXP days when all you needed to worry about was temperature.

It'll take a while to kill it, but increasing the voltage that much is not something i'd do. As for the value, it's crap. £66 for a heatsink not much better than a TT BT for twice the price same goes for a 9500.

Try their homepage: xbitlabs homepage. And, by the way, like I said the first time, that means it's not any better than a $35 Scythe Ninja, which is also better than a Big Typhoon.

You don't know how ignorant you sound... "all Conroe can hit 4Ghz" do you really believe that trash you just spewed out?

Too true...and very few people realize this. Even running a system on LN2 with -10c temps eventually 1.7volts will make it pop.

because half the heatsink is mounted to the cold side of the pelter, therfore, hurting it's own performance.

I am sure that a good high-end heatsink like a skythe infinity would put it to shame, or at least be a few degrees cooler.

I read a review on it somewhere that stated that the TT big typhoon even beat it when the fan was turned up to 2000rpm.

I wouldn't consider buying it

Interesting.

I am not even the least bit impressed.....
I have 3 heatsinks that i have tested on my p4 3.2EE with my p4 3.2 EE over cloked to 4.4.....
The Ninja and the zalman 9500 as well as the XP 120 all were literally the same temp at idle....and that is idle at 4.4 not 3.2.....

All 3 heatsinks underload only allowed for a 10c degree.....I believe all the load temps were under 40c......maybe even 36c.....

So as others have stated I also am not impressed as Bobthelost stated --
How does a 60W pelt cool a 150W chip, not to mention how does it do that while keeping the heatsink merely warm? I smell bullshit here.

First of all it doesn`t beat all other coolers.
Secind your making claims that the article didn`t even make
Third I can get the same temps or better using a Scythe Ninja or a Zalman 9500 or even a XP 120....

All my temps were under 40c and that is with my P4 3.2 EE over clocked to 4.4.........
Unlike others I am speaking from experience!!

Peltier was "feasible" with low-power CPUs, like the Pentium 2 and 3. After some threshold which I recall was close to the TDP of a Core 2 Duo, you would use more and more additional electrical wattage to withdraw heat from the processor, and you couldn't make the TEC more effective, since it has to fit the same CPU area, which is growing smaller in comparison to the older models. If LGA775 changes to something else that trims a few square centimeters off the cap area, it will be worse.

It appears to me that they have introduced these Peltier-heatpipe-hybrids especially because the Core 2 Duo models are in that feasibility range. At the same time, top-end heatpipe coolers are almost as good -- some even better by what I see here.

You are going to use extra power whether you use TEC or phase-change. And I'm wondering what the wattage draw would be on a phase-change cooler by comparison.

Finally, at least with heatpipes for air-cooling, the "number of things to go wrong" is practically zero, since the expected MTBF lifespan of a heatpipe cooler is at least a million years [taken from a white-paper published by a company which made heat-pipes for NASA.] Note that they only give you a 2-year warranty on the TEC. That could be for various reasons, but the various reasons for a rational company all derive from a "bottom line," and estimates of just how long they can expect a TEC device to work before either the TEC PCI controller or the TEC plates themselves malfunction.

Mostly -- think about your power bill.

For me, I'm going to build my Core-2-Duo using the technologies I chose for my Prescott system and my P4P800 mobo.

JediYoda --

You've had that 3.4EE for at least a year now. I might have thought you could over-clock it to a limit of 4.25 Ghz, or more likely to about 4.08 Ghz. How da h*** did you get it to run stable at 4.4? You're still only using a CNPS 9500 or other heatpipe cooler.

What memory modules are you using on that sucker?

The cooling is done by the heatsink, not the peltier. The peltier helps one move the heat from one face to the other. I didn't do the math to check this case, but this is the principle behind a heat pump system. If you look to an air conditioning system, you use less power to feed the system than the heat it is actually moving from one source to another. Typical thermodynamics...

I'm not saying the Amanda works, I just mean it could be a great product if properly dimensioned and executed. After the Xbits review, it doesn't look good.

 

[myocardia]

Anyone know what happened to OCZ's phase change system? I've been waiting more than 6 months for them, and have yet to hear anything concrete about a release date.

 

[Zenoth]

It's so huge ... I'd have to leave my current Tower open to install that thing.

Almost:

1) The amanda draws 60W, including two 120mm fans. Assuming they draw a mere 1A each on the 12V rail that's 24W gone, 36W left to move the heat.

2) Peltiers are horrifically inefficent. 50% is a good rule of thumb equation. In other words to shift 100W you need to put in 100W, all 200W now needs to be cooled by the heatsink. In our case you're not even managing a third of a high end P4D.
