Log My (second) Streacom DB4 build

[Raiju]

Started working on this build again. Modded the motherboard heatsinks so they can connect to outer heatsink with heatpipes.

Good to see the db4 still useful. Its arguably the most impressive looking and ambitious case design.

The Streacom heatpipe I had laying around blocked the motherboard screw so I replaced it with one I bent myself.

small update

Finally, first panel finished. Next stress testing.

Looks good!
Are you still using the Coollaboratory metal pad(s) as thermal paste for the CPU?

Yes, I only removed the bits that had oozed out just to be on the safe side.

Case was positioned suboptimal for cooling (I miss an angled hdmi cable) but the rest of the panels was off. Heat transfer was real good, the panel became too hot to touch.

Half hour stress cpu goes to 85C (had plateaued for 10 mins) vrm 57C chipset chipset 47C. Rest of temps all ok.

Idle after half hour 36C, all this with ambient temp of 20C.

All in all not bad, too early to tell if cpu is gonna need tweaking for long gaming sessions.

 

[Raiju]

I did not like the 85C, it sometimes can get 20C hotter in the summer here so 85C wont do.

After a lot of tweaking and testing and many clear bios later and bitlocker annoying the crap out of me I got a stable solution.

70C with 4.2 GHz all cores (smt enabled) and finally managed a ram of 3200 Mhz 16-16-16

1 hour test:

 

[Raiju]

This is going to need some puzzeling.

 

[Raiju]

Was not sure if this would work, die => metal pad => copper shim => carbonaut => heatsink. Tested a bit outside the case with a riser and I am happy, very good heat transfer.

 

[Raiju]

Hard bend, now I need to make 3 more.

 

[Raiju]

I finished the build. Gpu temps are great, very low idle no throttling full out.

Great result, is this 100% passive right now?
I imagine even a small, slow fan that turns on at upper temp-limits would make a HUGE difference to longer sessions.

Yes, it is 100% passive and adding any fan would defeat the whole purpose of this build.

That's totally fair, I'm very impressed

That's awesome! I'm currently working on a similar build... may I ask which tool you used to bend the heatpipes? I got a "breakline bending tool" from eBay but the bending radius seems to be much bigger than yours.
