Swiftech mcw6500 w/ pics and benches

[seedomo]

Installed the new MB and packed the socket with grease this time!
Also pick up a Maze block to get rid of the NB fan and also added a VGA block for the 6600 cause the fan was loud as hell. And the circle begins... my temps are now 12c higher so I just bought a thermochill PA120.3 to run with my Swiftech 220 and am wondering if I need to run them on separate loops or use my existing pump to run them both. Currently I use the 665. The price just keeps adding up. I guess I'll have plenty of rad cooling but where to mount it all, I don't know, best to probably sell the 220 and get a thin 120 for the VGA and NB and run them separately. More cash!

Southbridge heat... I thought I could just cut off the heat pipe and leave the SB heatsink on, but temps were 60 to 70c, with a fan on it! So I took off the NB heatsink fan off an A8n-sli board and it fit barely. I've ordered the EVGA SB fan (I hate fans damnit) but what else am I gonna do. Seems like I'm chasing my tail here... buy two blocks to get rid of the fans, and because of that I'm gonna have to add a fan.

I'm running right now at 3.6 at 1.5 volts without issue. CPU temp is 0 at idle but quickly goes beyond 50 on load. I've also measured the load for the PSU which is a Antec True Power 550. It is 270 idle and 375 under load.

While I'm sure lubing up, playing with grease and all that tubing is fun, if you actually want to get better temps GET RID OF YOUR TEC! You want lower temps yet you add even more restriction and heat with more blocks and another rad? You're making the problem WORSE, not better. You do understand what you're doing here, right? It's like you want your car to go faster and you keep putting premium gas in and then stick a banana in the tailpipe.

[seedomo]

I knew I would see an increase in temps, just how much, I didn't know. Now we all know.

[theteamaqua]

thanx for the lesson ... i was gonna get swiftech TEC block ... but then i realized that it might not be enough .. in which case startight water will do just fine

PS: if u have 2 PSUs.use the best one for ur comp, and the 2nd one for TEC... just use a u shape wire to short the 24pin connector. thats what i do ... i have my pump + fans on my Thermaltake 750W, and rest of my Thermaltake 850W (heh 750 cost me $150 last June i believe, and 850W cost me $189.99 @ frys)

[Duh]

TT ain t not good. for that prices I would have grabbed two pcpower ( 510 w turbo cool ). Not trying to be mean but don t use as a source for an argument that guy johnny bravo..err johnny guru :p

[theteamaqua]

huh? two pcpower only 510w?? dont know how much current it has over 12v rails , but 510w is just too small

also not sure what ur trying to say on that 2nd sentence

nvm just checked .. only 38A over 12v rails .. never see that PSU here.. frys do have the PC Power & Cooling 1000W though for a wooping $530

seedomo,
I have been offline the last couple days rebuilding my case and just got back a few minutes ago. You have been a busy guy since I last posted, lol! New motherboard, new chipset blocks, and a new radiator! And I thought I was busy just building up a new case, lol! Anyway it sounds like your results were a bit dissapointing? Sorry to hear that but as you probably know now theelectic is right!

Fortuenlty you have a few different routes to try out, you could just switch to straight watercooling to test out. You could also buy a more powerful TEC until (although it is more money they are quite cheap thankfully), having the extra headroom with a stronger TEC unit might help out because its' quite clean your now overpowering your current TEC plate. Although I've never run a TEC until it should be quite easy to replace the current plate with a more powerful until right? I am curious to see how this works out for you, since you have already spent so much money and spent alot of time on this I would probably opt to trying a more powerful TEC, but only after testing with straight water first, just to get a baseline (useful for future testing)!

It sounds like you spent some time trying to figure out if your current PSU was capable of powering your system and it sounds like you should be alright (by the way what kind of amps are your rails pusing on that Antec supply, do you know)? With that said my only other suggestion would be to scrap your old radiator and stick with the PA120.3, I believe it is certainly capable of removing enough heat for your system. Plus the added benefit of additional cooling capacity might be overshadowed by the additional restriction to flow (probably have to test to make sure but from expereince I think you'd be better off with a single rad)? Well good luck m8 and keep us posted, keep up the good work!

Actually, you will need to take the PSU apart and swap out the wires to lower gauge wires (usually PSU wires aren't rated for the large currents TECs draw).
Also, you want some load on the 5V and 3.3V rails so the 12V rail is stable. This is exactly why you want a meanwell or something like that.

[Duh]

nope, I meant to grab 2x 510w pcpower ( 650w peak) with 38 amps in the 12v line...or you could grab the one you mentioned, I am pretty confident it won t let you down.

another option would be to buy a silncer 750w which peak is at 825w and 60amps in the 12v

I think there is a 510w version in the FS section. Here I can get the same model at 3 times the price the guy is selling it :S

2 x 510 = 1020W .. right now i have 750 + 850 = 1600W , plus the TT 850W has 4 x PCI-E, total of 60A + 62A = 122A over 12v rails

but yes for TEC i think a single rail PSU would work better, then again TT 750W has 18A over 12V rails which is what swiftech suggest

[serialk11r]

Look, the wires will most likely burn, because they are not rated to pull the 24A that the TEC requires.

[theteamaqua]

swiftech says 18A
http://www.swiftnets.com/products/MC...tion_guide.pdf

Recommended installation for coldest temps: Connecting to a dedicated auxiliary power supply
�� The minimum requirements for a dedicated power supply are 25A @ +12V.
�� Your TEC module has been measured to draw 18 amps at 12 volts. We recommend using the “Meanwell S320-12” auxiliary power supply, which is adjustable at up to 13.8Volts, and will boost the cooling performance. The S320-12 is available on our website in the Thermoelectric accessories section.
�� You will need to cut and strip the wires of your TEC module in order to connect them to the terminals of the power supply
�� Connect the red wire from the TEC module to the +V terminal, and the black wire to the –V terminal as shown in figure 4 below.

is cutting the wire needed for normal PSU.. from the picture it seems like thats only needed for aux PSU

hey frozencpu has the 400w pelt ... should i get that if 226w is not enough ?? although it is 60x60 .. a bit bigger than the 50x50 from swiftech

If I use a 6500T and two MCW60Ts, does it mean that I should buy three Meanwell S320s ? And if I were to mount the Meanwells in the optical bays, how would I exhaust the PSU heat?

They won't handle a kentsfield, just to let you know The PSUs have fans built in, and I hear that if you take a small 80mm fan or something, they will run cooler and quieter (the internal fan is probably noisy).

[IanY]

So, you are saying that a MCW6500T cannot handle the heat of a Kentsfield. Philly Boy is saying that it can get a Kentsfield to over 3.9 Ghz. I just manage 3.75 Ghz, and I thought its already very good, but I don't have a TEC.

In that case, can a MCW60T's 188 watt TEC handle a 8800GTX ?

[IanY]

Another thing that I'm very confused. They say that an Enermax galaxy 1kW is ok to use, but a PC Power Cooling 1kW-SR single rail cannot handle the TEC? (I'm talking about using two more 1kWs that are separate from the PSU for the rest of the system).

[theelectic]

Put it this way, who would you believe, someone who has actually tried and used quad with that block, or someone who's talking out of thin air. Even Swiftech's own data shows that the 6500T will handle overclocked quads, albeit barely, and you're pushing into a range where straight water is better. You may end up like seedomo where you're overshooting the TEC. There's not much headroom to play with.

Another thing that I'm very confused. They say that an Enermax galaxy 1kW is ok to use, but a PC Power Cooling 1kW-SR single rail cannot handle the TEC?

No, this is exactly what Swiftech says about using an "existing power supply":

The unit can be connected directly to high-end computer power supplies. At the time of release, we have validated in our labs the Enermax Galaxy 1K power supply.

You CAN connect it directly to a high-end PSU. They have only validated the Enermax Galaxy themselves. Obviously, if the PCP 1k is similar/better is should be able to handle the load.

Again like in the other thread you started, you're better off using the Meanwell - it's smaller, cheaper, more efficient, etc. As Gabe from Swiftech has stated on many occasions, all you have to do is add another quiet 80mm fan on top of the existing one. That way more air is pulled out and the noisy internal fan never starts up. The extra heat that is generated should be easily handled by your case exhaust fan.

[IanY]

Do you know how many TECs a Meanwell S320 can handle? If I were to use a MCW6500T and two MCW60Ts, do I need two or three Meanwells ? How am I supposed to mount three Meanwell PSUs inside a case and yet exhaust all the pSU heat if they are stacked on top of each other?

Many thanks.

[Vinas]

You CAN connect it directly to a high-end PSU. They have only validated the Enermax Galaxy themselves. Obviously, if the PCP 1k is similar/better is should be able to handle the load.

The PCP&P 1KW outputs a max of 1100watts and continuous 1KW. Hard to believe there's anything it can't handle.

Do the math. The MCW6500T requires 18A @ 12V. Each MCW60-T requires 9.3A @ 12V. These figures are all from the Swiftech website. The S320-12 can supply 25A @ 12V. So you could get away with using two @ 12V, not three.

As for case mounting - better get a bigger case, mount them outside the case, or cut some big holes. Be creative. Whatever you do don't stack them on top of each other.

[seedomo]

So I swapped out the Swiftech 220 rad and put in the mother of all rads, the Thermochill PA 120.3. What a difference! I'm looking pretty good now at 3.9 using only 1.525 volts 1.46VDroop. CPU temp doesn't go above 37c. Cores top out at 51c. But whats great is that I'm stable at 3.9! Pretty close to my goal of 4.0. I think I won't need to run separate loops. I also don't really want to try the water only option since I've seen people using this rad running temps up to 70c. Can that be right? What are average temps to expect for people running straight water at 3.8-3.9Ghz? I can't image that they are able to keep their temps under 37c (CPU reading, not core), right?

[seedomo]

It sounds like you spent some time trying to figure out if your current PSU was capable of powering your system and it sounds like you should be alright (by the way what kind of amps are your rails pusing on that Antec supply, do you know)?

36A on the 12v rail.
I've also determined that I'm pulling 410 watts at 1.535Volts running at 3.9

[Duh]

2 x 510 = 1020W .. right now i have 750 + 850 = 1600W , plus the TT 850W has 4 x PCI-E, total of 60A + 62A = 122A over 12v rails

but yes for TEC i think a single rail PSU would work better, then again TT 750W has 18A over 12V rails which is what swiftech suggest

1- it s not 2x510 as its peak its over 600 w
2-psu s as many other things have a variety of qualities and TT is not top notch nor nothing similar

If I use a 6500T and two MCW60Ts, does it mean that I should buy three Meanwell S320s ? And if I were to mount the Meanwells in the optical bays, how would I exhaust the PSU heat?

hey pug boy :P no one said you should buy meanwell you can buy whatever you like at ebay for cheap like L33t who bought a 1kw psu for aprox $100+S&H IIRC

to cool down your psu you can use something like this

I'm teetering on the edge of stability. Orthos for 32 mins. using SMALL FFTs and then error. So I'm adding a pinch of voltage at a time to see what it takes to get me stable running it for an hour. With each .0125 increase temps rise about 2c. My CPU temp is now peaking at 38c. Fingers crossed.

[Duh]

I would change TEC and make it run confortably with the amount of wattage, amps and volts and would not play too much with voltage.. when you play too much with voltage, happens
