very cool 8)

[mihaiantonio92]

bravo frate esti tare rau !!!! la temperatura asta ii trebuie atigel :))) glumesc

[Alinstres]

felicitarile mele dumyyyyyy! esti un electronist pasionat si foarte foarte bun! ai viitor frumos in acest domeniu! vad ca esti capabil sa construiesti totul de la 0! inca o data felicitarile mele pentru realizari

[dumyyyyyy]

@Alinstres Multumesc foarte mult pentru aprecieri si laude. Cat despre facerea lucrurilor de la 0, nevoia m-a invatat. In orasul meu nu gasesti orice. Si am fost nevoit de multe ori sa improvizez.Se numeste "blestemul orasului mic in care nu gasesti nimic" De exemplu aceasta racire cu freon pentru calculator a fost lipita cu fludor in loc de alamire. Merge si asa dar trebuie avut grija mare la lipituri. Acuma ma lovesc de acelas blestem: lucrez la un CNC pentru mine si e greu cu materialele.

[Alinstres]

@dumyyyyyy Hai mai omule ca mi-a placut playerul MP3 si ceasul cu PIC16F din HDD si Sursa aia care este super!!!! sa fi sanatos si sa nu uiti ca esti roman si tara are nevoie de tine! esti si pe elforum? poate ne faci onoarea de a ne prezenta si alte realizari pe acest forum al pasionatilor de electronica!!!

cu stima si respect

[DusmanulCatalin]

cam care ar fi pretul daca ti-as cere sa-mi faci un astfel de sistem la comanda?soket am3

[Tiberiusprinceana]

merge bine la temperaturi scazute? stiam ca se blocheaza daca este frig

[dumyyyyyy]

@Tiberiusprinceana De un an sta la -10 grade(uneori -15. depinde de temperatura din camera) Si oricum... atunci cum iti explici procesoarele alea overclockate la peste 5ghz care sunt racite cu azot lichid?(azotul lichid raceste pana la -170*C) Deci este posibil. Daca se blocheaza nu este din cauza procesorului, ci din placa de baza sau hard(sau amandoua)

[jojuae]

WHat about condensation? At -36c there has to be some liquid forming 0.0

[dumyyyyyy]

@jojuae Y have -36*C without load (just chiller in air) When is attached on processor the temperature is -10*C in summer time and -14*C in winter time(depends by ambient temperature of my room).And of course, y have no condensation,because y have isolated very good the whole part (with 3-4 layers of bublefoil). Y have done this insulation experiments with the chiller outside the case, and even at -36*C y have no condensation. But special treatment y had to do at the motherboard to support this.

[jojuae]

@dumyyyyyy OOOHHHHH I forgot about insulation. >.> My appologies.

[kostass321]

acum a mai ramas sa pui berea la rece,ca doar ai mini frigider :P

[kostass321]

Now u just have to put some beers inside to join them cold :P

[bujie2008]

nota 10+

[cristysigoo]

Crezi ca ai putea ansambla toate componentele astea intr-o carcasa mai mare ca sa mai aiba loc si cateva cutii de bere???

[Lucians78]

Foarte tare omule!!

[dumyyyyyy]

@sharkyrivethead This week(if y have time) y will create an flikr accout to upload some high resolution photos of all my inventions(including freon cooling).When its done, y will put sole links. Bye..

[MrDonFlavi]

Ce procesor este inauntru?

[dumyyyyyy]

@MrDonFlavi Un AMD Athlon 64 3000+ care merge pe default la 2ghz.... E un single core din 2005. Pe soket 754.A fost mai mult un moft.... nu o necesitate.... Ca inainte imi statea la 40 grade.....

[Slabule]

bravo ;)

[Achilles5391]

foarte tare !! bravo frate, esti bun... te respect ! ai putea sa faci o afacere... probabil ai castiga bani frumosi :D... oricum, felicitari..

[h3xyournightmare]

superb! ideea asta e geniala! in primul rand iti raceste procesorul si in al doilea rand e si aer conditionat mai ales pe timpul verii!!! ar fi fain daca ai face chestii din-astea pe comanda si pe sisteme si mai smechere (de la 4nuclee in sus) inca o treaba...te-ai gandit sa faci cumva sa porneasca compresorul odata la cateva minute? :P daca piesa de pe procesor care absoarbe caldura e bine izolata ma gandesc ca tine destul de ok procesorul sub 0 grade si asa poti oprii compresorul pt economie:D

[dumyyyyyy]

@h3xyournightmare Multumesc pentru aprecieri dar situatia nu e chiar asa de roz precum pare:compresorul merge non stop(atata timp cat calculatorul merge).Diferenta e ca procesorul meu genereaza constant caldura, si prin urmare trebuie constant extrasa si evacuata.La frigidere e izolat termic tot, asa ca odata racit congelatorul, nu mai intra caldura acolo decat foarte greu!(deaia compresorul porneste doar din cand in cand!)Temperatura procesorului e in medie -11 grade(-14 iarna si -10 vara)

[h3xyournightmare]

@dumyyyyyy da..inteleg ce spui dar eu ma gandeam de exemplu sa faci un montaj astfel incat sa porneasca compresorul cu intermitente. ce propun eu e sa faci in asa fel sa ai un interval intre -10 grade si +20 sau 25 grade in care compresorul sa fie oprit cred ca poti sa-i dai un maxim de 40grade ca nu se intampla nimic. nu cred ca urca asa de rapid temperatura de la -10 pana la +30 grade.ca sa poti avea un timp mai mare de stop pt compresor ar cam trebui sa izolezi exagerat zona cu procesorul!

[blackmissu]

Salut. Cam cat te-au costat toate materialele???.si de unde ai cumparat acel radiator de aluminiu ?

[JoostyBoy]

@dumyyyyyy Great job! I've got a few questions. Does the pump stays on all the time? (think so) Isn't that noisy? How much power does the pump consumes? Can you tell me where you get R134A from and does your "comfrigerator" need to acclimatize?

Very cool! Take good care of it! ;)

[dumyyyyyy]

@JoostyBoy The"pump" its a compressor.And yes, stays on all the time. The power required for compressor its only 76w(at 220v ac) .The freon R134A can you buy trough internet for example from air conditioned repairing companies. (its a gas, and pressurized became liquid) . This freon cooling system require about 2-3 minutes to stabilise itself (when start to cool from 25*Celsius to -10*Celsius). And thankyou for appreciations!

[JoostyBoy]

@dumyyyyyy Okay, thanks a lot. This is much more efficient than a peltier. I hope I could reproduce your work when I've got some spare money and time ;)

[Orexll]

@dumyyyyyy DUDE, you need to put that with a 2500k or a 2700k and you could be part of the 6GHz club!!!

[onlyreallifematters]

@Orexll expensive if he kills the mobo or the cpu then, hence the older amd cpu he's using in the vid. but yes, could be awesome!

[superpacker]

Theme song: OceanLab - I Am What I Am

[dumyyyyyy]

@superpacker Thank you for the hint, now i know who sings this melody.Y have cutted from a larger track(60 minute) from a online trance radio.

[IC3WOLF1389]

BRavo frate ai avut vreo problema cu el vreodata ? oricum gj pentru  proiectul acesta felicitari U ARE A GoD

[dumyyyyyy]

@IC3WOLF1389  mi-a facut fente soketul de la procesor.E 754. Am facut gresala ca n-am pus de prima data vaselina dielectrica in el. Pusesem ulei siliconic.Era bun si ala da' a curs.. O alta poblema e ca pana incepe instalatia sa raceasca trec cam 2 minute.Pana atunci procul mi se ducea in 45 grade.Am rezolvat problema cu un microcontroller programat sa-mi intarzie pornirea placii de baza timp de 3 minute, ca sa porneasca direct cu procul rece(cam 10 grade, dupa aceea scade pana la -10 in medie)

[Scorpion9709]

Nice very nice ! and tell me what temperature its in your room when u use pc?

Tare foarte tare! si spunemi ce temperatura ieste in camera ta cand folosesti pc-ul?

[dumyyyyyy]

@Scorpion9709 Now i have 23*C and my CPU have almost -11*C.

Acum am 23 grade Celsius si procesorul sta la -11 grade.

[vladutz45]

Cel mai tare sistem de racire vazut de mine pana acum .Din cate vad este foarte prectic un asemenea sistem fata de azotul lichid cu care nu poti umbla asa de usor si nu il gasesti oriunde.Dupa parerea mea ar fi o alternativa perfecta in cazul unui overclock ''extrem''.

Bravo ai facut o treaba foarte buna!!!

[digerpaji]

this is so COOLLLLLLLLLLLLLLLLLLLLLLLLLLL­LLLLLLLLLLLLLLLL......now if i may ask how much to what frequency did u overclock the CPU to????

[dumyyyyyy]

@digerpaji My motherboard hold-me back. I have achieved 2,5ghz from 2ghz original clock.Keep in mind that is a ddr1 memory system with a motherboard from 2005 (asrock k8 upgrade nforce3 soket 754 amd athlon) Single core. The cooling system y made was only a. personal wish... Just curiosity to do that. And with this cooling system i have learn a lot. Just for the record: all the information to do that i have found on the internet.No previous experience have with freon cooling!

[digerpaji]

@dumyyyyyy thats so bad ass...you think the same can be achieved with a liquid nitrogen compressor?

[dumyyyyyy]

@digerpaji Liquid nitrogen compressor? You kidding right? With liquid nitrogen you will achive up to -196°C! Do you want to do extreme overclocking? Believe me,does not worth it! At such temperature the mother board will not last much time! Even my motherboard has crashed once! The pcb has fail during many cycles 20*C->40*C-> -13*C! (Before to do some bug-fix in the design. Read the earlier comments to undestand what was happend) Your only solution with nitrogen cooling is to keep computer on!

[digerpaji]

@dumyyyyyy but u would also have a regulator monitoring the load and predicted temperture, to supply the absolutely neccesary amount of liquid nitrogen.

[Jymmmmy007]

very nice!!! best PC colling system!!!

[dumyyyyyy]

@Jymmmmy007 Thankyou for appreciations! And yes it is! after almost 3 months from building everithing works ok. I don't know if you know, but this cooling sistem draw only 76w from the 220 power grid!(an peltier element draw over 100w and its inefficient too). The only problem its when i start the PC, the freon cooling system require almost 2 minutes for the pressure build up and start cooling.In the meantime, the procesor produce heat, and reach almost 45*C.To prevent that, i have programmed a.

[dumyyyyyy]

@Jymmmmy007 (continued) I have programmed an microcontroller to do some timing : First when i start the PC, first thing the microcontroller power up the freon cooling first, and after 3 minutes send a "ON" command to the mother board to start the PC. Like this, the procesor never exceed the ambient temperature!

[florynbn]

dar nu am inteles de la ce frecventa ai plecat si unde ai ajuns..ma refer la cpu

[gabydelafocsani]

gabygaby38 idul meu de mess as vrea sa vorbim putin de chestia asta daca iti face placere multumesc !

[gabydelafocsani]

chiar merita investitia? eu te felicit pt realizare....ai avut de munca !

[dumyyyyyy]

@gabydelafocsani m-a costat foarte putin! chiar mai putin ca la o racire pe apa(in jur de 400 de lei) Tinand cont ca eu sunt electronist si mi-am facut tot eu si partea de comanda a compresorului, proiectarea, executarea etc.Am acasa multe componente recuperate de la te miri ce de-a lungul anilor. Si sa-ti spun sincer? nu merita.Decat daca esti vre-un obsedat de overclock.La mine a fost mai mult ambitia de a face asa ceva. Am facut pentru mine cu scop educativ. Si nu regret nici o clipa.

[catalincelmaitaree]

dumy admir ce ai facut poti sa bagi si u id catalin_cata_7 in lista,as vrea sa stiu si eu niste detali...Multumesc!

[Mariusel007]

Esti tare Dumy ...tino tot asa....apreciez ca lucrezi elegant

[donmoshu]

bravo !~



[ady689]

foarte smecher !

[mrmagnetyc]

cel mai tare , dumy le ai la toate

[dumyyyyyy]

@mrmagnetyc multumesc pentru aprecieri. As fi facut mai multe daca aveam materiale si scule mai bune. Da' cu "meseriasii" astia din Curtea de Arges nu mai ai incredere sa-ti faca nici macar un surub la strung!
