Enermax pits latest ETS-T40Fit cooler against a 350W coffee pot

[HEXUS]

The new Enermax ETS-T40Fit CPU air cooling range includes three slim models.

The test, which used one of Enermax's new air coolers with its fan running at 1800RPM, ran for over an hour and a half. By that time the boffins probably wanted another cup of coffee, so gave up.

Love it.

I'm not 100% sold on the scientific value of the test reaching 99% but never quite boiling, in the context of a CPU cooler, but it's quite a clever marketing stunt.

Well this sounds like a pretty good cooler, and it sounds like they are gunning for the 212 EVO around that price point, with the added selling point of specifically avoiding blocking the DIMM slots where possible.

That said, we'll have to wait for proper benchmarks to see how it compares, but if it performs equally, takes up less space and is easier to fit the the 212 Initiation ritual, I can see myself using them in future.

If water boils at 100ºC and this thing dropped temperatures to 99ºC... that doesn't sound very impressive.

That means my 75ºC CPU at full tilt will be, what... 74ºC?

Point is it was cooling and preventing a 350 watt appliance from boiling water - so roughly getting rid of said 350 watts easily. As the kettle NEVER boiled it's probably actually getting rid of 360 watts given the margin of errors you'd see

No, that means you skipped physics classes at school.

More likely it wasn't on the syllabus - They taught such useless junk irrelevant to us back then (unless you were specifically going to be a maths teacher, or something).

But unless it has a number of other heatsinks to compare against, that is pretty meaningless from an end-user perpective... unless said end user is into O-level physics calculations, of course!

I get the impression it's not going to be something I give up my w/c loop for though, right?

[3dcandy]

Doubt it - but as Saracen said it's a marketing ploy that works quite well

Bravo

350W of dissipation? Maybe Enermax have seen next year's AMD "performance" cpus... LOL
Sorry, couldn't resist.

(And before anyone has a go at me about being an Intel fanboy, they might want to check my system specs)

Your post is exactly why this was pointless. Not enough people understand thermal dynamics to appreciate the magnificence of this

EDIT wow this was an arrogant post, sorry. Not intentional, I don't fully understand the science behind it myself, I just know it's a great achievement. What I meant was not enough folks are fully versed in the intricacies of electrical output converting to heat and convection etc. etc.

Enermax boffins attempted to boil the espresso maker with a ETS-T40Fit perched on top, it got close to 99°C

Hmmm, if the coffee got to 99°C using a "cooler" perhaps they should call the ETS-T40Fit a heater? Just sayin'. ;o)

No offense taken - At least you didn't insult my schooling!
TBH, we didn't do much of that in physics anyway, along with numbers not being my strong suit in the first place (only got a C for maths and physics), but it was more than a couple of decades ago and I've not used any of it since anyway - hence asking why this was supposed to be such an amazing achievement and what it's likey to mean in the real world.

Near as I can see, it takes a load of heat off the CPU... but then just vents that heat into the rest of the case where it is at the mercy of your exhaust fans anyway.

From some freeze framing, with no cooling (by the way this works out to ~150W effective heating power assuming 250ml water @ 10C/60s):

40C 1:43
50C 2:50
60C 4:00
70C 5:08
80C 6:27
90C 7:35
100C 8:43

Now for the cooler:

40C 1:30
50C 3:30
60C 4:55
75C 7:23
80C 8:40
85C 10:54
90C 13:22
95C 18:27

So the heating time was about twice as long until (presumably) it got to the point where the cooler was sinking heat fast enough that the heater couldn't do any better. Note that at lower temperatures the water is heating up almost as fast, possibly there's less convection? It looks like they managed to get lucky and find a coffee heater that was juuust underpowered enough that at 95-98C everything was in thermal equilibrium.

The peel and stick rubber pads for fan installation could limit the swapping of fans a bit.
Hope it comes with a decent quantity.
