Hello guys, is there anything that I can purchase to improve airflow/temperatures in C4-sfx v1 with a 5090FE. I haven't configured it yet, waiting for SF1000 - SF750 seems to not be compatible. Or maybe the temperatures are not that bad? (I'm going from 4080FE to 5090FE).
Hi, normally you can start a RTX 5090 FE with a SF750, but it will fail on load. Afterwards it depends also on your CPU, storage.

Unfortunetly the 5090FE was faulty and it didnt start even with SF1000, thank you for the feedback guys.
I am wondering how compatible is the new air tunnel bracket from v2 with v1. If it is, could you make this bracket solo-purchasable Dan? (it's probably a "no" but I had to ask)

hmm 3D print to the rescue perhaps?

I have a separate temp sensor connected. It is cooler. Plus anecdotally, my "cave" does not get as hot during gaming sessions.

10th anniversary of DAN Cases
10years.jpg


DAN Cases GmbH was founded 10 years ago today. The journey began in 2016 with the A4-SFXv1, which played a key role in establishing the sandwich layout within the SFF segment. In 2022, we launched our first collaboration with Lian Li: with the A4-H2O, we made the sandwich layout more affordable and accessible to a wider audience.

In 2023, we reimagined the “reversed classic layout” with the C4-SFX, setting new standards in the SFF space as well as in GPU cooling. Just a year later, in 2024, another collaboration with Lian Li led to the A3-MATX, which has since become one of the most popular cases on the MFF market.

This year also brings exciting developments: our third collaboration with Lian Li, the B4-MATX, is planned for Q2 and will support both vertical and horizontal desk orientations. Later in the year, the C4-SFXv2 and C4-MATX will follow, combining compact volume with high compatibility and strong cooling performance in their respective categories.

Finally, I would like to sincerely thank all supporters, readers, partners, as well as my family and friends. It has been an exciting and rewarding 10 years with DAN Cases—and I look forward to what lies ahead.

Best regards,
Daniel <3

Thanks for sharing!
Variations between the mini ITX & micro ATX MB are interesing (SFX PSU position and CPU cooler location).
With micro ATX MB on Intel socket, dissassembly of the MB would be mandatory to replace the CPU cooler.

What about the thermals with the BIG GPU? It seems the GPU is blocking the airflow overall.
Hardware Canucks noticed that on the B4 review.


I would assume having a "SFF" GPU + intake fans is the best solution for the C4 too, isn't it?

I notice the actual volume of the C4-SFX v2 chassis is almost 15L when the feet/base section are taken into account...

Thoughts towards running the chassis without the feet/base section (using a set of felt or rubber pads to keep from scratching whatever surface the chassis is resting on), and having whatever exhaust there will be from the PSU getting sucked out the side by the 140x25mm fan...?

Maybe even include another set of screw holes above the existing ones for the PSU bracket, so it could be moved up a bit to allow for more exhaust air flow, I would use the GPU support portion of the GPU air pass-thru diversion dealio, but not the diverter section, so that would allow for the shifting of the cable height coming out of the PSU...?

LOL, I just realized I would probably have to block off the bottom of the chassis (at least under the PSU) to ensure any exhaust from the PSU was diverted out the side fan...?

Thanks...!

I loved those brenchmarks! Very instructive. I like the idea of the plastic duct to isolate the CPU cooling from the GPU exhaust.

Are we now 9 years in on the C4 SFX?
I haven't looked for the original thread, but think it started in 2017...
I think grandchildren may arrive sooner than the V 2.0.

Please don't read this as criticism of Dan, it's a bit of gentle humour.
I appreciate we are living in a complex and fast moving world.
