RIP BATTLE: Modded RTX 3090 Overclock & Optimus Water Blocks (#RIPPAUL, #RIPJAY)

We're preparing to RIPJAY, but first, we need to get past Paul. We've leapt far up the Port Royal hall of fame with just water, not even chilled, and some hardmods for our EVGA 3090 FTW3 cards.

As a reminder, our objective in this overclocking battle series is always to try and advance ourselves and learn. In this episode of our RIPJAY (JayzTwoCents) and RIPPAUL (Paul's Hardware) challenge, we're trying to learn more about hard modding GPUs, starting with shunt modding an EVGA RTX 3090 FTW3 (specifically, learning more about soldering on these boards). We may venture into more hard mods following that. We're using Optimus Cooling water blocks for the cooling, and as discussed in the video, they're some of the best blocks we've ever tested. The blocks are made in Chicago and these are early prototypes, so we didn't get any instructions or pre-cut thermal pads for ours, but that's not a problem for us. The final version will include both of those things, however.

    • @MOTO/R/SPORT NEJ alright cool thanks for the info. Good food for thought. Thanks for the well written indepth reply. Starts to get to the question of is it even worth it to use a chiller at that point of just go cold forreal an use LN2.

    • @Skoopsro It’s not that much power to cool down even a crazy CPU or GPU. 5000 BTU is about 1.5 kW of cooling for and can be done using about 500watt of power from the wall if you want just below ambient fluid temps. Now as you try to get much less than ambient your COP goes to crap and you might need a pretty big chiller but I think even something like a deep freezer is still around a COP of 1 so you need a freezer that’s rated to pull around however powerful your setup is on average. Now I think I’ve seen the SLI3090 setups pulling about 1kW from the wall total. Meaning you need another 1kW freezer/chiller if you want negative -20C fluid and probably only around a 500 watt rated chiller if you want ~0-10C That’s for SLI 3090s..... any sort of pleb build could run in basically a standard freezer ... IF .... you can keep the condenser/compressor reasonably cool.

    • @Lawrence Timme yes

  • Tbh, if you suck a soldering, then soldering surface mounted components are not the best thing to so with the wrong equipment. If you are going to do some SMD soldering anyway, get a hot air soldering station and a component holder. But the best thing is to learn to solder and _get the right equipment_!

  • Flux helps to keep the metals from oxidizing which facilitates a cleaner stronger solder and connection. Without flux, it will oxidize and produce gunk that starts to build up quickly and won't produce a strong solder.

  • In welding flux keeps atmospheric air from contaminating the weld metal ;)

    Richard SalazarRichard Salazar26 gün önce
  • Flux keeps oxygen away from the joint. The problem when joining two metals is oxides. As soon as a metal surface is exposed to air, the surface will turn into an oxide layer that will melt at much higher temps than the base metal and keep anything from adhering to it. If you keep oxygen away from the joint when you're soldering or welding, the it won't form an oxide layer and the surfaces will "wet" with molten metal.

  • I think those cooling mods can get better, but for now are just are really impressive vanguarding tech right there. If somehow Gamers Nexus team can manage to put one of those in between two linked cards... maybe they can find the way of cooling desired.

  • flux keeps the joints cooler and cleaner reducing risk of burning the board/components and adding a protective coat to the solder joint so its less prone to degrade from oxygen

  • Jesus is God Exodus 3:14 (God speaking) And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. John 8:58 (Jesus speaking) Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. John 10:30 (Jesus speaking) I and my Father are one. Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. John 1:1 & 14 1 In the beginning was the Word, and the Word was with God, and the Word was God. 14 And the Word was made flesh (Lord Jesus), and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. God called Himself "I am" and Jesus called Himself "I am" which proves He is God in the flesh. Now we're just waiting for Jesus to return for those of us who follow Him. Titus 2:13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Revelation 1:7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen. Revelation 1:8 (Jesus speaking) I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty. Revelation 22:13 (Jesus speaking) I am Alpha and Omega, the beginning and the end, the first and the last. --- There Are None Righteous Romans 3:10 As it is written, There is none righteous, no, not one: Luke 5:31-32 (Jesus speaking) 31 And Jesus answering said unto them, They that are whole need not a physician; but they that are sick. 32 I came not to call the righteous, but sinners to repentance. Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. Ephesians 2:8-9 8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.

  • From someone who has worked in the electronic manufacturing business for over 15 yrs. I can assure u for the soldering u are trying to do u don’t need the board preheated. It’s probably doing more harm than good depending on the type of flux in the solder roll u are probably burning it off before it haze a chance to react. The flux is a cleaning agent, each time u heat cycle the solder joint with ur iron ur creating a cold solder joint that’s why they look dull. I would recommend Turing ur iron temp up a lil and doing away with the board preheat.
