437 watt TEC exposed as fake. - Overclock.net

Ultrasonic2 (muffy) · 06-10-08

I’ve always believed the 437 watt TEC to be incorrect but I’ve been unable to find any manufactures details giving me genuine data. I have believed the 437 to be incorrect because while moving 437 it was achieving a delta of 74c which is far higher than anything else.
Using the number below I believe the 437 and 74c delta to be at a rated temp of 50-54c or twice the normal rating of 26.85 (300 kelvin)
I might point out that the below reason given for the 360(437) TEC being able to handle more voltage and current than what it should do is NORMAL and ALL TECs can exceed the rated data when the temp is increased..

--------------
The next revolution in TEC cooling! This peltier fits most manufacturers water blocks based around the 50mm x 50mm TEC, and moves nearly as much heat as the 437W TEC! Testing on a Danger Den Mach-4 TEC water block show that it produces nearly the same results as the 437W TEC on the Wintch Labs Arctic Web.
Although this is a 36 volt TEC, it was tested with the Meanwell PSP-600-48 power supply and found to work great.
In all reality, the 437W TEC is a 360W TEC that can handle a higher voltage and amperage so that it can move a calculated 437W of heat. It is still manufactured as a 360W product.
Here are the specifications of the 437W TEC from the manufacturer:
Umax : 25
Imax : 24
Delta-T Max : 66C
Qmax : 360
Measurements : 62x62x3.55
Resistance : .75

Here are the specifications for the new 50x50mm 345W TEC :
Umax : 34
Imax : 16
Delta-T Max : 67C
Qmax : 345
Measurements : 50x50x3.95
Resistance : 1.40-1.50

it is still a shame it doesn't say what temp these TEC's are rated at. i assume it's 300 Kelvin.

if anyone could post links to the actual manufacture of the 226 and 360/ 437 TEC that would be great!

interesting....

REP+

edit:shame on you though, double post :P

**ira-k** · 06-10-08

Thats not a new TEC, its been on the "Arctic Spider" site for 6 months at least, with that same run down......

...340 Watt Peltier

Ultrasonic2 (muffy) · 06-10-08

o yeah i know .. but thats what the post says so i thought i wouldn't change it

**ira-k** · 06-10-08

It might be a good one to try out, I haven't talked to anyone who has used it yet...At 50x50mm it would save having to buy a special block to, thats alway a +...

Ultrasonic2 (muffy) · 06-10-08

yip .. it also makes mounting 2 of them directly to the CPU more practical. which is the route i might take now, in a million years when i build my milling machine.

hows the load temps on your BE with the 437 watt block you running there?

**ira-k** · 06-10-08

When I can keep the BE rig running it will Prime load at OC to a C or two over with a 1.46 v-core at around 3400mhz...I have that actively cooled bucket res and it helps a lot with load temp's...

Peltiers are often rated at 25c and 50c (and as you say are often at ~27c). Those 437w elements are no doubt rated at 50c.

Also sellers often qoute bizarre numbers for the power like Imax * Vmax which is rubbish.

The resistance of that new TEC seems very high, I may need to look into it more.

Edit: also, I think it was wintsch labs that made up that 437w number from estimates, it wasnt a manufacturer rating.

Ultrasonic2 (muffy) · 06-11-08

Imax * Umax someone on this forum decided to call this Pmax and i've run with this.. People on E-bay seem to use this rating all the time. To magically transform a 2 watt Qmax TEC to a 2000 watt unit.

i also found the resistance of the 345 unit to be strange....

Id love to find the manufactures details on these TECs but that seems very hard
