MCX4000-T really good?

[Jag]

Hi, this is my first post in this forum, so bear with me.
I hope someone can throw a light on this.
I want to use an air cooled pelt, the Swiftech MCX4000-T, but I would like to know some more about it.
So:
1.º Feathers and Unregistered (air cooling thread) talked about the Swiftech capability of handling 100watts. The bottom line is: can it or can't it?
2.º Is this a viable option? I don't want to use WC just yet.
I mean, if I adopted an air duct to cool directy the cpu, and use a 92mm fan?
If someone uses this Pelt cooling system please say the facts.
3.º What are the average temps I can expect to get from it, using a PIV 2,8C or 3.0C?Even overcloking the temps are better than with a simple air cooling heatsink?
4.º does this really works?
I you would give your objective inputs I would appreciate.

Check the swiftech webpage. They have a graph detailing the performance of the unit relative to applied heatload. 100 watts falls outside that range. Also, bear in mind that their applied airflow is 80cfm (loud fan), and that the unit is discontinued.

the MCX4000 used a 226W TEC (17A @ 12VDC)
will handle 100W so long as the air is sufficient !

your temps will depend on the amb air temp @ the fan inlet, and the amt of air the fan pushes (and the CPU ect.)

So, my plan is to upgrade a MCX4000 to a MCX4000-T (with pelt).
Do you think this is a viable solution?; i.e, the results (in theory, or in practice) are generally better than with simple air colling with the same cooler?

you can try, not too many enjoy drilling and tapping 8 holes with 4-40 threads

I want to try, but with certain guarantees first, not some empirical statements, because that's why I asked you first place.
For example a prescott 2.8E (89 watts thermal load), with this MCX4000-T at amb. temp of 28ºC would give me a temp. of around 34,32ºC (by my calculations).
In your opinion is this a good trade-off, I mean with a wartercooling setup (MCW6002 and a 22501b kit) could I have the same temp ?
In terms of investment, does it pay-off or not?

[BillA]

you'll not get a simple answer to that question

a good trade-off ?
as YOU assign the weighting to the parameters, how can anyone make that choice for you ?
noise ?
cost ?
space/case required ?

and your goals are ?
lowest temp ?
highest OC ?

all these are your choices, what I think matters not
no guarantees in the OCing world, get good gear and install it correctly
I would opine that you cannot get as low temps with WCing, but such depends on your skills at converting a MCX4000

[Jag]

Ok, I follow you.
Well, the starting point is:
Case: Lian-Li PC 60 - 2 x 80mm intake; 1 x 80mm exhaust top; 1 x 80mm exhaust back
Board:Asus i875p
Cpu:Prescott 2.8E (89w thermal power)
Cooler and acessories: Swiftech MCX4000-T, with fan Y.S.Tech 120x120x38mm, 131 CFM @ 2800 RPM, 45 dBA, .66 amps, 7.92 watts, 12 volts DC, 3-pin connector
I stiil have to get the adapters for the fan.
Option: MCW6002 with 22500-B kit. - I don't know if the Swifty 6002 waterblock will accept Pelt or not.
Extra: Air Duct to the cpu
Cost factor: I've compared the costs envolved (WC and TEC - Swiftech gear), and they are basically neck and neck - hence the doubt!

GOALS:
- Avoiding large fluctuations in cpu temp. For example, OCers with WC in Winter ramp up the Mhz, but in the Summer have to lower them due to the high temps (45ºC).
So, like maintaining a constant(?) cpu temp is better achievable with TEC?
- Stability, running the cpu as cool and as stable as possible.I'm not in the Ocing race.
Ocing is tricky, because I've read that the boards mosfets aren´t enough to handle Prescotts, and therefore get pretty hot (ABIT, for one).
Aparently the new boards (LGA 775) will have twice the number of mosfets. So, it's something of an open question mark - no guarantees as you wrote.

Finally: knowledge is easy to get, but wisdom/experience is something else - so your opinion counts.
In the near future, as the thermal requirements of the new cpus tend to be even higher, Pelt solutions will be the best way or not?

[BillA]

if you are not chasing the max OC, go with water (for less noise if nothing else)
and a LOT easier to implement

the MCW5002 will remain the wb for TEC heads, should have an AMD version eventually

by future you mean . . . . . ?
the step beyond heat pipes is already known, Swiftech plans on being there

[Jag]

Yes, it seems the best option for now, and eventually later I can add the Swiftech chiller to the WC setup.
By future I mean two years from now. By the look of things, "a change is gonna come".
Thank you for your help.

ive got the 4000-t on my 2500+ barton and its ok but puts off a TON of heat into the case my temps dont run too spectacular either (with a 92mm tornado at about half) im planning to ditch the heatsink for watercoolign in the next few weeks

But, what is you OC, ie. how many watts, and what are your amb. and cpu temps?

[chrisbmx68]

cpu temp was abo 86f prob 120ish internal diode (who knows if either of those tems are accurate) and with side pannels off case temps were close to ambient. The cpu is running 2.3 with slightly over stock vcore i forget exactly what it is. The tems were good but with the sides on and the meanwell in front of the intakes and with stock 80mm fnas case temps got well into the 80's. This is in an antec soho case i removed the lower front hd rack and now i have 92mm intake and exahust and the meanwell mountd on top of the atx psu
