Triple peltier chiller - Page 14

Thing is yea it's dual heatpipe but it won't cool well due to the small heatpipe a are in the centre and not covering the whole thing I have tyres the triple heatpipe 4870 cooler with 120mm 70cfm 240 volt fan that worked good but I'm not sure how well them dual pipes will do but have to try it to find out as everything with peltiers biggrin.gif also how you planing to bolt them together don't the screw go into both them wink.gif
Also yea the 775 was fun overclocking I had a e8400 touching 5ghz at 10*c load at 1.6volt but asus p5q deluxe how ever it's spelt lol but yea I even had a 771 Xeon in a 775 with tin foil and double sided tape to make 2 pins switch position on the cpu wink.gif only 3.5 ghz at 523fsb x7 1.46 volt was a nice cpu dual core but had a lot of l2 cache then I went am3 and everyone told me my lil Msi 970a g43 will catch fire explode kill my cpu but has it? Nope I've not ever had a problem with it lol I would of stuck an fx8100 8core in there but then it's 4cores with HT anyway pretty much and the Xeon will have a slightly better overall edge on an 8100 and cheaper buying a board and cpu as a 8--- new is over 130ish so hoping it will be worth it

You are right about the twin heatpipes not covering the whole TEC, but the base is lapped flat so the aluminium all touches the TEC too and it has fins soldered directly to it, so with a 140mm 70cfm fan it will blow air through the two heat pipes on the outside edges of the alu fins and also blow air on the fins in the centre of the heat sink. The heat sink doesn't have as much weight as the intel stock cooler but I think with the 30mm or 40mm adapter plate and 2 lots of thermal paste the *c/watt of the intel heatsink would be much worse than the *c/watt of this little thing. Plus you have to remember I'm only looking at dissipating about 80w through each of these heat sinks at a 20*c delta, so I can be 15*c above ambient on the hotside and still drop my total loop temps down to ambient I think. Here is a look at it with a 12715 40mm TEC on it.



As you said, its not all in contact with the heat pipes but as the base is all nice and flat and the base has alu fins soldered to it and the heat load is very low and also I do away with extra thermal paste and copper adapter plates I feel the *c/watt lost through this heatsink will be better than that stock intel heat sink would have been and the whole TEC hot side should be closer in temp than the outside edges of the copper adapter plate with intel cooler would have been. And once again I'm just lucky to have 2 of them laying around so I can test both options. On that picture you can also see the 4 mounting holes. they are in a 53.9x53.9mm spacing, identical to my GPU water blocks, I took the standoff posts out of the heatsink and I can now bolt through from the top side of heat sink with the fan off straight into the GPU mounts, I had to buy some M2x16mm screws to reach the threads in the GPU block with a TEC sandwiched in between.



This also shows the screws going through (just the stock ones though, too short with a TEC in there, got some cap head 16mm M2 high tensile screws coming.

Yeah I had a P5q deluxe as well. Kept my Q9550 at 471 FSB and 8.5x multi for years rock solid, was going to try the 771 quad xeons in it but really I was ready to move away from the platform, just too much IPC loss compared to new platforms, my old quad Q9550 was slower than this dual core G3258 in multithread and gets destroyed in single thread.

Honestly I am going to buy an AMD ZEN system no matter what I think, I like AMD it's just been hard to justify a purchase on their current platforms, ZEN should be a big step in the right direction and even if they are slower than Haswell or even Ivy Bridge I think they will still gain some market share back from the Bulldozer fiasco.

Good news, my Asrock Z87m Extreme4 arrived, both my G3258's are ok and working fine. Bad news though, I jumped the gun and already bought another G3258 just in case they were both dead, so I now have 3 of these little suckas. Thats ok though as my newest one has the lowest VID, first one was useless with VID of 1.123v for stock speed, second one was a good one with VID at 1.081v, thats the one I lapped, this third one is even better with a VID of 1.074, might have a 5ghz 1.45v chip here, hopefully less. I'm going to punish the one I lapped under the TEC for a while and see what I can get out of it.

If I can get the Gigabyte mobo RMA'd I'll sell off the G3258 with the worst VID packaged with the gigabyte mobo and this 8gb kit of kingston value ram. If the G3258 that I lapped is satisfying my 5ghz desire with reasonable volts I'll keep that and sell the best one as it is brand new and only tested for a few hours.

So, I'm back at it. Time to insulate the new asrock mobo then I think I have everything I need to get TECing

biggrin.gif lucky my vid was 1.07 v stock speed but just didn't like 5ghz very well at all hope you get a nice voltage and my new Msi is here it is like new.. The I/o isn't even open all the sata ect are still new and its number 58 with a overclock pass of 197fsb 19x multi on an Es i7 and passed all the tests so I'm happy hope I get a 220fsb chip maybe I will go from 2.58 to 4.5ghz with a nice voltage biggrin.gif all 8 threads active or even a 3.6ish I'd be happy with honestly as it will out do my fx4100 at 4.8ghz so yea I am onto a cheap upgrade under £85 and a lot faster good bang for buck for what I want I only got 8gb ram and an old Gtx 295 so it isn't Amazin but good enough but I need to build a controller now as I'm not sticking anything in the cpu socket or coating it as i got it out the box with not 1 mark or anything maybe I'll just use kneeded rubber eraser around the socket n cup then insulate the waterblock and make sure it's a nice seal around it so no condensation build up anywhere

Nice looking board, sounds great! Yeah I've been thinking about just using art eraser in centre of socket, not on pins and eraser around the socket and skipping the LET, but the LET I bought peels off pretty well so I think I'll still use it. I'll be putting heaps of neoprene around the water block and around the socket and on the back side of the motherboard.It's the dielectric grease in the socket that really bothers me, seems like it would be a pain to get it out without damaing pins, unless acetone just dissolves it without damaging the plastic socket surround. I have the controller but I'm not sure what temps I want to set it at yet, I want to be able to set it as cold as the 12715 can hold the CPU at 100% load to get 5ghz+. I haven't tried OCing the lower VID one yet but the lapped one did 4.9ghz on water. I think it's a stretch to get one of these to 5ghz 24/7 with reasonable volts, and honestly for these chips my "reasonable voltage" is 1.5vcore hahaha, especially under the TEC. One other thing I like about this asrock motherboard is the dehumidifier setting, I think I'll turn it on when I use the TEC, it will evaporate any moisture before it can damage any parts, we'll see how effective that is, but the main reason I want to use it is that it basically builds in a delay before it boots the PC, so power supply and pump, fans and TEC will turn on prior to boot, so it has a chance to freeze any moisture and get cold enough to boot at a higher CPU OC. I may be wrong about the way it works though.

Fingers crossed you can get 4ghz+ out of that setup. My brother just bought a 5820k so I've got itchy fingers to jump on a socket 1150 Xeon E3-1281V3 4.1ghz chip, but they too expensive for only being able to OC to about 4.3ghz, but 4 cores/8 threads at 4.3 would be a nice balance long term, but not much fun for using with my TEC setup.

nice nice nice, that xeon gonna be saweettt!!! yeah I wish they would just put decent heat sinks on motherboards without all the flashy bits. I loved the old heat sinks on my P5Q deluxe and on my striker extreme 680i. They were really quite good at keeping temps under control with a bit of airflow on them. That one actually looks pretty decent too.

I have fantastic news, my TEC beast is up and running. I;ve done a marathon day of Insulating, making stuff to fit the blocks, re-doing my water cooling loop, testing a few times along the way to make sure I hadn't killed anything after insulating and putting dielectric grease in the socket (I actually slightly bent a pin, luckily I saw it through the grease and was able to bend it back before I put the CPU in) I bled my water loop after I refilled it. Then I plugged the TEC controller in while I was bleeding the loop, I have the temp sensor on my cold plate. Ambient temp is 25*c. The TEC pulled my cold plate down to 15*c set point within about 5 to 10 seconds, very reactive. I let it run for a few minutes, I didn't have any fans plugged in on my rads, just water circulating through the loop. I was satisfied with that so I turned it all off and plugged everything in. Booted the PC, everything worked fine. Got to desktop, opened hardware monitor, stock 3.2ghz CPU idle temperature is 15*c biggrin.gif cold plate is 14.5*c. I am in love with this thing haha. This controller is worth every single penny I paid for it. It is fast to react to loads, keeps things right where I want them to be, cold plate varies about 0.2*c maximum. I'm just testing the highest temp set point right now. I ran aida64, highest core temp is 23*c with 14.5*c cold plate temp. I wasn;t sure if I got the whole water block, TEC, cold plate mount right, and also, that thermal grizzly was ridiculously thick, very difficult to spread on so I think I've ended up with too much thermal paste. It might actually be better to use something thinner and easier to spread on just to get a thinner layer on each side of the TEC.. Regardsless, I;m extremely happy it all works and I didn't kill anything and my insulation seems to be doing a great job although I'm most likely not below dew point yet.

buy this and when you check out ask them to configure it for minus 15*c to 15*c set point range. its worth every cent!! http://www.ebay.com.au/itm/231704893134?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

and a heatsink for the mosfet http://www.ebay.com.au/itm/151506789498?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

and a thermistor http://www.ebay.com.au/itm/141580417124?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

this is the perfect budget set point temperature PID PWM controller, it just works!
