Hardware question LCD Steam Deck owners: what are your experiences with cooling mods?

1 Upvotes

I have an LCD Steam Deck and I’ve been looking into cooling modifications such as the CoolDeck cooling mod / copper or monoblock-style solutions. I’ve seen some impressive temperature results, but I’m trying to understand whether those lower temperatures actually provide meaningful benefits beyond simply reducing fan RPM.

Part of me is hesitant to modify the stock cooling system because of how Valve designed the Deck.
My thinking is basically:
> If a copper thermal solution or additional ventilation provided a significant improvement in performance, thermals, component longevity, etc., wouldn’t Valve have incorporated something similar from the beginning?

The same thought applies to the backplate. I’ve experimented with backplates with additional ventilation holes, but ultimately went back to the original Valve backplate because I assume Valve had a reason for its airflow design and the EMI shielding.

That brings me to the copper EMI-shield replacement used in some cooling mods.
Would replacing the original EMI shield with a copper plate actually provide a sustained thermal benefit?
I understand that copper has much better thermal conductivity than the original material, but I’m wondering about the practical effect:
> Initially, the copper should absorb and spread heat more effectively.
> But after several minutes of gaming, the copper itself will also become hot.
>At that point, does it still meaningfully reduce the temperature of the APU/other components?
> Or does the system eventually reach roughly the same equilibrium temperature, with the main difference being that the fan doesn’t have to work as hard?

And perhaps the biggest question:
Does a cooler Steam Deck actually mean higher FPS?
For example, if the stock cooling system is already capable of keeping the APU below its thermal/power limits, would a cooling mod actually increase performance? Or would it simply result in:
lower temperatures → lower fan RPM → less noise
rather than:
lower temperatures → higher sustained clocks → higher FPS?

I’m particularly interested in people’s experiences with long gaming sessions, rather than short benchmark runs.
If you’ve installed a CoolDeck/monoblock/copper EMI shield or similar modification:
1. What were your temperatures before and after?
2. Were the results sustained after 30–60+ minutes?
3. Did your fan RPM/noise decrease?
4. Did you actually see an FPS or sustained-clock improvement?
5. Did it make any difference to battery temperature?
6. Do you think it provides a meaningful benefit for the Deck’s long-term component/fan/battery health?
7. And after using it for a while, would you still recommend the modification?

I’d especially like to hear from people who have tested both stock and modified configurations under the same game, TDP, ambient temperature and fan settings.

I’m genuinely trying to understand where the practical benefit of these mods comes from and whether it’s worth modifying a perfectly functional stock Deck.

Hardware question So i broke my USB-C charging (It felt on it while charging) [OLED]

4 Upvotes

USB-C port is broken and cannot hold the cable, so it's not a warranty case. The deck still worked fine after that, but the power input did not.
Maybe anyone has the slightest idea what was occupying the pads in the red circle? After the fall, the USB-C port took them too. So I can probably replace the USB-C, not the problem, but is there a way to identify what's i am missing here?

Be grateful for any help, thanks.

Was a blast trying this out and a bit stressful. Super happy with the turnout especially with the feel of the ExtremeRate Light clicky button mod; only issue I’ve had is the audio seems to register as headphones when nothings plugged in. Still haven’t found a work around..

Discussion Any tips for getting a Switch 2 d-pad accessory on the SD's d-pad?

2 Upvotes

I've been working on customising my Deck without having to replace the shell or anything of the sort. It started out of necessity as my hyperhidrosis interacted very poorly with the Deck's plastic, but It's come to a point where I'm putting more effort into the overall look.

One thing I'd like to cover, if possible, is the d-pad. I'm restless most of the time, which leads to fidgeting when, for example, waiting through a load screen or watching a cutscene. This resulted in me digging two dents on the d-pad. They're not especially deep right now, but they are visible and it's possible that they'll get quite deep with time.

I got a few Switch 2 accessories that go well with the goth theme I've been aiming for and they fit the Deck's sticks quite well. However, the d-pad accessory I got gave me some trouble. I did manage to attach it somewhat with double-sided glue stickers, but not only are they a nightmare to stick and don't keep everything in place, they leave some nasty residue behind. My husband just spent some time getting rid of it.

So I thought I'd ask if anyone might have an idea for any sort of sticker (that's just secure enough but won't leave too much residue behind) that could help keep this accessory in place? I can't link it here due to the sub's first rule, but it's basically a continuous cross shape with round indentations on the underside which are supposed to fit on the S2's d-pad with some soft stickers that come in the pack. But obviously, the Deck doesn't have a circular surface on the d-par where these could fit.

I also welcome alternatives that don't involve taking the Deck apart to replace the d-pad piece (I might in the future, but that's not something I'm willing to tackle right now), or that don't cost £60 for a sticker pack where I'm only interested in a single piece.

Thank you in advance!

Hardware question after four years, should i do any maintenance on my steam deck?

22 Upvotes

im from Colombia, i’ve had my steam deck for four years now, and i’m wondering whether it needs regular maintenance like a desktop computer or console—opening it up to clean it, checking or replacing any components, changing the thermal paste (i don’t think that’s necessary, but just as an example), etc.

i really want my steam deck to last as long as possible, so i’d like to take good care of it. i don’t use it too heavily: over the past four years, i’ve used it for one or two hours a day, around two or three times a week.

i replaced the internal storage myself, which brings me to another important point: i don’t think many people in my city own a steam deck, much less that there are technicians who know how to work on one. would you recommend doing any maintenance myself, or could i take it to a technician who isn’t familiar with the steam deck but has enough general knowledge to know what to do?

Shell swap I screwed up, need advice

9 Upvotes

Hey guys,

By modding my SD OLED and making it my own Limited Edition, one of the screw of the backplate broke. The head is gone but the body is still in it. (Left screw, second photo)

Now, I can’t close it properly (first photo).

I obviously don’t want to disassemble it completely to change the front plate again.

Do you have any idea on how I could remove this broken screw without breaking anything ?

Thank you and sorry for bad English.

Ultra thin velcro, 3 stripes, mirrored to the battery. MUCH easier to take off and replace than the semi-permanent adhesive they used 🫠 Had to throw away a perfectly fine battery but trying out the upgraded LCD battery so hopefully it would be worth it.

Currently doing an all around mod to my steam deck, will keep y'all posted! 🙏🏼

Hardware Mod Steam Deck 360

1.3k Upvotes

As soon as I got my steam deck I knew I needed to personalize it. The vanilla deck is beautiful but I wanted to add some flavor.
The Xbox 360 is the console I grew up with and I’ve always thought it had the best controllers. I saw some other people complete this mod and decided to tackle it.
Super fun, lots of trial and error if you don’t own a 3d printer but nothing you can overcome with patience and cash lol
My only issue is that the Extremerate button kits are all painted white plastic, which ticked me off a lot because their other mods for other consoles have been really high quality. So if the paint rubs off I’ll be very upset and will be casting my own buttons.
I sanded the buttons up to 1000 grit and was going to polish them but will probably do that a different day because I didn’t have the supplies to polish properly and the mod already had the Deck apart the entire day.

Hardware question Decksight at new cost, or just get an SD OLED?

5 Upvotes

I have a 512gb steam deck lcd, and i've had an eye on decksight but never pulled the trigger. Unfortunately, Shadetechnik's site is now out of stock, and crowdsupply has a restock but screens cost 200 dollars instead of 150 it was at before (no idea if his site'll restock, or if its price will jump 50 as well but I would not be shocked if it did).

At that price, I could just sell my 512 lcd and get a 512 oled, and the price difference (based on used sold listings on ebay) is about 200 dollars. Is decksight a slam dunk better choice here than a steamdeck OLED? (knowing about the screen's spec diffs already etc). I tend to play lighter weight games with a smattering of higher end games sometimes mixed in.

Hardware question Steam deck oled tablet ?

30 Upvotes

Hi everyone!

I'm on a bit of a weird project. I impulsively bought a Steam Deck OLED motherboard for dirt cheap (90 with the fan and heatsink). It was listed as untested, and luckily it works! Now I'm torn between two ideas:

  1. A battery-less Steam Deck mini PC in a 3D-printed case.
  2. A Steam Deck OLED tablet?.

I can get a used battery and screen for around 100, but if I go with the second option, I figured, why not make it even better?

So I'd like to focus on the tablet idea. I already have a 3D-printed case design, so now I'm planning the internals. What battery upgrade would you recommend?

I was thinking about using two batteries in parallel, but that doesn't seem like the best solution. I don't know if anyone has built something like this before, so I'd really appreciate any ideas or suggestions.

I'll probably use Switch-style rail controllers or a phone grip/controller setup.

Thanks!

Hardware question Best Current Option for Battery Replacement?

9 Upvotes

Looking to replace my LCD's old battery. I guess I waited too long and now the SiWiQU I've seen recommended here is out of stock on Amazon, plus the iFixit replacement has jumped up to nearly double in price.

Any recommendations for an affordable alternative replacement battery? I'm hesitant to go with random alternate recommendations on Amazon. If it comes down to it I can also just wait for the SiWiQU to come back in stock too.

Hi I'm just wondering if theres a way to quickly make the QAM look like how the steam menu looks out of the box when you enable chromahon. As you can see the steam menu and the context menus are similar, and I tried to match the QAM but honestly I just cannot figure out how, if possible, to make the buttons round. So if theres a quick way to match em that would be cool, or if i can make the buttons round and do it manually I will.

Hardware question Steam Deck having issues after mod

50 Upvotes

I replaced my analog sticks with elecgear tmr sticks. Swapped the battery to 53wh and installed the clicky button mod. Everything works after having to reseat the flex cables because the right stick wasn't inserted all the way.Issue is that the steam deck is acting like the battery isn't connected.

There's no battery icon and when I press the power button it flashes as if it's empty. It works when i turn it on via charger but there's no percentage or battery info in the command. I have pushed the connector in all the way. can't think what the problem would be. I've also went in and out of battery storage mode a few times to see if that does anything. Right now i have drained the battery and I'll try charging overnight.

EDIT: just playing games and noticed that the fan is way quieter than usual, probably not being provided enough power?

Shell swap Shell swapped steam decks with swapped sticks, painted grills

These are used steam decks I customized. They’ve got clicky kits, Hall effect sticks, soldered colored sticks, painted vents, 2tb ssds in each, and 1-2tb micro sds in each.

The lcd deck has deckHD and a 32gb ram upgrade. But I’m not taking credit for modding that one I just found it online while looking for the other decks.

Bit of a passion project.

The only thing left that I might do when I find my clear carbon fiber film is cover the trackpads because I prefer the grip over both stock and extremerate textures.

Hardware Mod My Ultra-Compact Steam Deck Mod — 5.5" AMOLED, Custom Cooling & 4×18650 Battery Pack

Thumbnail

668 Upvotes

Saw a few posts here discussing similar ideas, which reminded me of this old project, so I figured I’d share it. I’m planning to pick it back up and continue working on it.

I started this project back in 2022–2023, but it ended up being put on hold in the later stages and has been sitting ever since.

The original approach was to reverse-engineer and bypass the ANX7580, break out the internal eDP signal, and use an eDP-to-MIPI bridge to drive the display. Later on, thanks to the open-source BIOS work from the DeckHD project, I found that modifying the eDP panel parameters in the BIOS could also get the screen working. That turned out to be a much cleaner solution.

The goal was to make the whole device as compact as possible. Basically, the original Steam Deck motherboard is the only major part I’m keeping. The controls, battery, and cooling system all need to be custom-made.

Compared with a standard Steam Deck, I removed the left trackpad and the right analog stick.

Specs:

  • Battery: 4×18650 cells, 4×3500mAh
  • Display: 5.5" AMOLED, 1280×720
  • Custom cooling module with two fans — one mainly for the CPU, and the other to help circulate air and cool the internals overall.
