PS3 Expected Delidded PS3 Temp Queries

[Checkity_CheckYoSelf]

Bulk filter caps smooth out voltage ripple, which improves efficiency. Aging capacitors could case a processor to work harder to do its job, even if its not bad enough to cause a YLOD. So replacing with new TaPol arrays of adequate specification could result in lower thermals.

On all of my A model consoles hold steady around 68C with a fan speed of 28-35% using webMAN mod. That's with MX-4 and MX-5 delidded. The best you can hope for is sub 75C at 30% with near stock curve. But I would tighten that up. webMAN mod is nice, but I prefer editing it with the SYSCON so it's permanent and not in software where it can screw up (which I've had webMAN do before. It overheated without spinning the fan up higher! I never figured out why).

Also the silicon lottery can swing your chips temps +/- 2-5C. A binned chip can run much cooler, which could explain @nCadeRegal's temps. Although they are unbelievably low, as in I literally can't believe it. He's told me before and it's inconceivable to me his 90nm RSX produces less heat than a 40nm RSX...but I'm not inclined to call him a lier. Must have just been incredibly lucky!

Yea i've since kind of shifted my theory to leaning towards heat sink contact being one of the main heat issues after working on my A model, and a G and an H model. I've been doing essentially the "eraser mod" but instead using 2mm thermal pads in the place of the eraser, and have seen some pretty dramatic results in temps, especially on the G and the H model. That G model I could hardly keep at 68, without pushing 80% fan speeds, which i've never seen on any of these consoles. I even de-lidded the Cell on that one since that was acting like the culprit. After doing the eraser mod (I did actually use the eraser on that one) I got it chilling at the 68 temp range, keeping the fan somewhere between 30-40% most of the time, which was pretty dramatic in my opinion. I also was able to get my A model to chill more in the 30% fan range, keeping webman at 64 I think, which previously was pushing 45-50% fan speeds. That one I used thermal pads in place of the eraser.

Yea that console was and is one of a kind. It kills me I haven't been able to get it going again. I have heard nands are finicky, but never had an issue till now. I've tried all options in recovery, they just black screen and it sits there. I swapped another ps3 drive into it and it just does the same. I haven't formatted one on a pc yet. I'll try that today.
I still can't grasp why updating from cfw to ofw caused this? It has to be a bug in that cfw 4.87 of evilnats.
The Temps on that console are insanely low. My last a01 would hit damn near 80 running the same settings with replaced top paste. I have not touched this one at all other than removing the hard drive the other day. It's super low use, that's all I know about it.

When updating from cfw to ofw you need to do it via safe mode or you will have issues like your having,
that being said I don't know if you updated via safe mode when this happened, but I definitely standby what I recommended with swapping hdds /format hdds.
Hopefully it's a hdd issue and you can get it working again

To update from cfw to ofw you need to do it on safe mode or you have issues, but as you said your son updated not yourself that may have been the issue, as I said try multiple hdds and format a hdd and hopefully you will have it working again soon

I have noticed that the 19 blade fan can cool the console at a lower RPM than the 15 blade fan. So the 19 blade fan is quieter = better IMO. I think some A models shipped with 15 blade fans, although I haven't been able to confirm that independently. Out of 7 A models I've worked on only the GameStop premium refurbished unit had a 15 blade fan. So they may have replaced it. Regardless that was one of my first mods to that console. And I have done thermal tests with both fans to confirm the 19 is better. So I don't know where the skepticism is coming from.

Just for laughs I'll show you my Ps3 cech L in a arcade Namco 357b chassis, temps after nearly an hour of playing gta 4

Not too suprised. That model has 65nm RSX & CPU. Get them out of the cramped case with more breathing room and it can cool more efficiently.

Actully more the fact it has a totally different Heatsink and twin 5inch fans as it was ment for arcade use all day long

A guy recently did a very nice test of all the different fans that would fit in the CECHA01 and he had a lot of nice data to back up the 15 blade fan being superior.

His numbers for the 2.20A version of the 15-blade fan are consistent with what I noticed, but I did use the 2.65A D14F-12BS1 01H1. The 19-blade fan can keep the RSX/CPU under 75C at 25-28% fan speeds (33.8-37.5 DB), whereas the 2.20A 15-blade fan required 35% to do the same (37.6DB). Hoever, that's the behavior I saw with my 2.65A version. His numbers for a 2.65A version would be better, but but the higher RPM at 25-28% make it louder than the 19-blade fan too. Although for that the temps were lower. So if your metric for "superior" is cooler for a a slight increase in noise, then yes that would be better. But that wasn't my experience with a D14F-12BS1 01H1.

His data suggest that the D14F-12BS1 01H1 would be the best fan. Cooler and quieter than all the rest. Instead my subjective experiment with that model required higher fan speeds and noise to cool compared to the 19-blade fan. That's at idle at least. And that was enough to make me switch back to the 19-blade fan. Makes sense to me that the most powerful fan (2.90A) can force more air at lower speed than can a weaker fan.

I wonder if it's just due to the fan lottery.

EDIT: I haven't serviced these fans either. They probably need new bearings and lube. So I probably never got a perfect test. Only a subjective one.

While the temps are not great in my opinion, I have seen worse. It's likely they've not got the IHS plates lined up correctly or applied to much thermal paste and it's creating uneven pressure (they are really sensitive). I have been doing a few C03's in the warmer weather here in the UK and I can 9 times out of 10 get it to stick to 60-65C in GT6 or TLOU with 29% fan and 55-60C with 34% fan. Idle temps are usually in the low to mid 50's with those fan speeds.

Dude how 29% stays mid 60s on a 90Nm console playing TLOU? WhT paste and method are you using and do you have case mods?
