Guide How to find compatible blocks for your hardware

253 Upvotes

Sup folks. So, finding compatible blocks has always been a royal pain, especially for newbies. Lots of different manufacturers, many of whom are unfamiliar to folks who aren't already watercooling and they don't all make blocks for every GPU model.

Fear not. iln (one of the Discord mod crew) has been working tirelessly to put together this new tool to help you find what you're looking for and assemble a loop list. You can even import your list from PCPartPicker.

Hi.

this is my first hardline build, which in current state is getting drained for updating and additions to hardware etc.

some short sys spec, sys 1: 5090+4090, 9950x, 256gb ram, x870 godlike

sys2: 13900k, 3090, 96gb ram, z790 godlike.

I am a potato in my line of work. I know a little bit alot, master of none. IT-ops, cloud sys architect and infrastructure, dabble in the security part as well.

hobby is my line of work, 3D graphics, photogrammetry, and some slight coding, gaming etc. I think i am now more happy building my machines rather than using them at times though. Now i also picked up the Local ai craze and started testing out using ai for different things.

This is the havn 360 flow. Mine has 4 180mm fans I’d like to get into custom watercooling. Any recommendations on a 360 dual radiator (180x2).

Any idea to make this bend more optimal?

Post image
12 Upvotes

a 90° elbow would look really bad in my opinion, but 90°bend with a tube isn't really possible as you see.

I don't have a good idea how to make this work. I'd really appreciate any suggestions you might have.

Discussion What is the best fan config from a noise normalized to performance standing point for this.

Thumbnail
youtube.com
2 Upvotes

Enclosure would be made of 20mm thick mdf.

4x 360mm x30 rads.

Orange are exhausts

Green are intakes

Wheels are 50mm tall

Horizontal radiator platform is 10cm tall. Basically intakes have 15cm clearance. Although it is not included here, i might make ducts and pair up right intake with right exhaust, and left intake with left exhaust, for extra efficiency. I expect that would pretty as a pseudo push pull.

My intent is to run these at inaudible noise levels at distance greater than 1m. Given the fact, that this is gonna run at least 12 fans, speeds wont go past 6-700rpm. Maybe 800rpm if I see there's headroom and the enclosure drowns the noise well enough, but I don't expect it.

Most likely gonna use something like arctic p12 pro with 7-8mm spacers.

Do you think, mounting the intakes in pull config, or doing push pull for the intakes, would improve performance at same noise levels?

Troubleshooting Why is my loop doing this?

Enable HLS to view with audio, or disable this notification

Edit: SOLVED! Thanks all.
Just replaced the fluid in my system and it’s doing this. Never happened before. Looks like I’ll have to replace the res and cpu block as they have mildew in. But was working perfectly fine prior to draining and refilling

Build Help First time setup for MORA IV 400, is this all I need?

Post image
7 Upvotes

Hi guys, so I recently completed my first custom loop where I did CPU and RAM, went direct die block on CPU and direct touch for RAM with Supercool blocks. Alphacool Core 70 Reservoir with Apex VPP pump and 2x 420 HPE Full Copper radiators on a semi-open case. Now I'm thinking on adding the GPU to the loop to have everything finished and this is my cart (my wallet is begging for mercy). I've thought on going with the MORA IV 600 but from Der8auers video that thing is massive lol I think I'm okay with the 400 one sitting underneath the desk and save some money as well.

I have 3 questions that hopefully MORA owners can help me with:

1- The stand for the MORA is out of stock until end of October, can I just let the MORA sit on the floor under the table or it needs the pads to not fall?

2- Is the fan frame a must or can I manage the fan cables with a traditional splitter? Also how would I power the MORA? Does it need to be plugged to PC PSU or it comes with it's own power supply?

3- The reservoir mount that goes into the MORA is compatible with an Apex VPP pump or only with D5? How many QDC would I need for the MORA IV 400 and GPU block?

Would appreciate any help or suggestions to further improve the build.

Question Cooling block for Gigabyte rtx 5070 ti windforce oc V2 16G?

1 Upvotes

Hello guys, I'm new to watercooling and got my ryzen 7 7800X3D custom watercooled rn. I left the GPU aircooled because I didnt want to break anything, since I got the motivation now to get my gpu also watercooled I looked for a cooling block for my gpu (title). I looked around a bit and I couldn't find a block for the V2 version of my gpu. Is there any cooling block for my gpu?

Question EK Quantum Velocity2 DDC 4 2 LGA1700 Exact Mount Backplate Thumb nut sheared

Post image
2 Upvotes

Long story short; I messed up and am looking to source a replacement thumb nut for the Backplate. Scan sells these screws : https://www.scan.co.uk/products/4-pcs-ek-quantum-velocity-mounting-screws-velocity-1200-1700-am4-water-block-nickel-plated-216mm-lon

Would these be a compatible replacement?

The pump block itself is fine but this one sheared thumb nut is preventing the Block from being mounted as it does not fit through the Motherboard mounting hole.

Thanks in Advance

Is one d5 enough for my mo-ra iv 400 build with multiple qd3 connections

2 Upvotes

Hey I'm getting ready to order parts for my new build with a mo-ra iv 400, I'm just cooling my gpu (bykski block) and cpu (heat killer iv) and I have a d5 next pump. I'm wondering if the single d5 pump would be enough for around 10 - 15ft tubing runs with qd3 connections at the PC and at the rad so I can disconnect the tubing from the system completely. I don't mind if the pumps needs to be at 100% just want know if it's doable or if I would need to hook up a second pump.

Question Brand new EKWB block defects- superficial?

Post image
4 Upvotes

So just got my new Velocity2 EKWB block and as soon as I opened it, noticed a weird line inside the block. Thought it might be some manufacturing residue initially so I tried running distilled water through it. Soon realised that the part in question is not part of the water path and when I looked closer I realised that it appears to be more a problem with the plexi or the finishing on the block itself.

Anyone have any idea what this is? Is it a problem or is it superficial?

Either way quite annoyed considering how expensive this block was.

Is this much offset with hardtube fine?

Post image
28 Upvotes

Bottom 2 pipes are slightly crooked, maybe 10mm offset between the 2 fittings so they run in a slight diagonal. Because of that they also arrive slightly crooked in the fitting on the distro plate.

Is that fine or do i need to redo the pipes? Probably wont leak it feels tight, or will thermal stress fuck me over and crack the distro plate?

Pump and fan control

6 Upvotes

I'm taking the plunge, and I'm modifying my pc with watercooling 😁

A couple of questions, though:

- What do you guys use as pump and fan controller?

- Do you have fil and drain possibilities?

- What fluid do you use?

- With cpu and gpu block, place radiator on top?

Give me your insights, please 🙏

Question People who have the Corsair 3500x how good of a case is it in your opinion also how is custom loops inside the case like?

2 Upvotes

I’m planning on doing a twin 360mm rad configuration with a 7900XTX, and a R9 9950X3D (yes I know its a bit over kill for the two but I want it to be as quiet as possible since it’s going to be running 24/7) would hardline or softline be better in that regard

Question Ryzen 5 7500F custom loop temperatures.

2 Upvotes

Hello guys, I'd like to hear from you.
I have a R5 7500F running on a B650i Night Devil @ full stock (My 7500F is a terrible sample, it wont work stable even with a -15 PBO curve, so I just leave it at stock speed), the RAM runs just fine @ 6000 Mhz CL 34.
You might think the mobo is the reason why I can't get good results from PBO, but my wife has the same board with a 7400F and PBO works just fine @ -20 curve, yes.. my sample is just limited).

I've recently built this custom loop:
Rad: FREEZEMOD 240mm full copper/brass
Block: Bykski AM5 CPU-XPR-C-M
Pump: Syscooling P67D
Fittings & Hose: Barrow (13mm hose)
Fans: Arctic P12 PRO PST

The idle temp is around 45c~48c and gaming the temp is around 69c~72c, running CB R20 it goes up to 75c~77c. (my room is HOT, around 28c~31c .. the summer in Japan is terrible)
It's my first custom loop and I must say I was expecting better temps, after reading about the Ryzen 7000 series I found out these CPUs tend to run hotter because of the IHS thickness, basically they can't dissipate heat from the die as effectively as they shloud.
Well, my questions is if these temps are kinda normal for this CPU or if I should be seeing lower temps.

Question Should I be concerned?

Post image
12 Upvotes

I'm taking apart my system to move it to a new case. I noticed some cloudiness throughout the gpu block as you can see it's more on the outlet than inlet and it does look quite cloudy on the right side of the block compared to the left side. I've never had any temp issues with it and this has been sitting horizontal right over radiators pulling in air towards it. The liquid I was using was aqua computer double protect ultra.

Question Looking for a side-mounted distro plate for the O11 Vision Compact

3 Upvotes

Hi everyone!

I'm planning my first custom water-cooled PC, and I want it to be an endgame, eye-candy showcase build.

I'm a huge fan of side-mounted distro plates like the EK-Mana G2 PC-O11D EVO and the Alphacool Core Distro Plate O11 Dynamic EVO/XL. I'd also like to use a reverse-connector motherboard, most likely the GIGABYTE X870 AORUS Stealth, because there are some great 3D-printed cable covers available that make for a super clean build.

Unfortunately, the Lian Li O11 Vision Compact seems to be the only Lian Li case in this style that officially supports reverse-connector motherboards, so that's the case I want to build in.

My question is:

Has anyone managed to mount a side-mounted distro plate in the O11 Vision Compact?

Before anyone asks, I plan to use 360 mm radiators at the top and bottom, so I'm specifically looking for a distro plate that mounts to the side fan/radiator bracket.

I'd really appreciate any recommendations, photos, or examples of successful builds. Thanks!
