Well, it's learning how to behave now.  
After acquiring an Antec P150 case, I can now safely run the aforementioned "burnt" computer at a comfortable 48degC. I have a new heatsink and fan coming in the mail, and my noise issues should soon be non-issues.

That's toasty unless you mean the GPU. Mine runs about 10C above ambient.

Having said that I never measured mine until I flowered it but I know you can push up on 70C at the cost of MTF.

It's 49 right now (13 above ambient) - with a crappy heatsink and a bad thermal paste job, which I will have to fix later\ when they show up in the mail. But it's a damn sight better than the 58 it was running before the new case.

Gosh you're in toasty climes; us reptiles rarely break 20 ambient (so I'm running at 29C). 13 above sounds more than reasonable. MTF from 58C is orders better.

36C woo.

I should rephrase: the ambient temperature of the case is 35C; the ambient temperature where I live is about 18C (if I did my conversion correctly).

There's nothing about this case that's cool :-(

okay - it happens I have an Antec Sonata, and my Dad has something almost identical to yours (also Antec).

Today it's 25C inside the house.

CPU: 30C
Mem: 31C
GPU: 50C
GAM: 46C (Graphics Memory)
HD0: 41C
HD1: 43C
HD2: 43C
Core: 27C

There's a two Zalman flowers (one on the CPU and one of the GPU), powered at low speed, plus eight air-cooled fins on the GAMs.

I'm using SpeedFan for the stats. If you're not using Windows, I apologise as my Linux experience is limited.

If you have a fan on the front of the case I'd remove it. I've not noticed such things helping anyone. The air pulls fine even through the filter.

On the back I use two fans, the PSU's and a 2nd 6". Both blow out the back. Also, if you have the lid off, put it back and it knackers airflow without it. ACPI on the BIOS and job-done.

Does that help at all?

I'll try it out when I get my new heatsink. This should help quite a bit, actually - thanks!

Also, this is the first time since I was six that somebody has used the word "flower" around me to mean "something which flows or makes things flow". It's just a little strange, like seeing the word "house" and suddenly forgetting that you've ever seen those letters in that order before.

Well, some of those coolers do *look* like flowers, or at least petals. I think either would be applicable.

In theory you should be able to make some decent gains by poking around. I don't think the case is as bad as you think.

Oh, I LOVE this case. Compared to the old aluminum one I had, this is positively heavenly. Most of the work left involves parts that won't show up for a while, but the case is the least of my concerns now.

After going through the AMD specs, the maximum operating temperature is 85C. That's RIDICULOUS!

Which means that my new max temp of 52C with the quieter heatsink means I can make it even more quiet. Hrm.
Virtual Travellervtraveller on April 18th, 2007 06:26 am (UTC)
Yeah - I did kinda say that. It's very dependent on where your temperature sensors are placed though. A CPU core of 85C doesn't mean you can let the rest of the board get to close to that level otherwise you won't be able to cool *their* heat generation efficiently.

Maximum speed normally alters MTF (Mean Time Failure) so you don't necessarily want the processor to burn like the sun. It will however slow down on its own if too hot so that it generates less heat. To be honest, you can't get a h/w engineer out of bed these days unless a layer of skin is left of the device by touching it.

Think about other things in the case. My GAM doesn't seem reliable over about 50C; very randomly sheering the screen and needing a graphics mode switch to recover it. No BSODs or hard crashes, just something freaky with the dual access to the VRAM modules.

I tracked down the problem in a pocket of hot air caught in the bottom of the machine. Removing a blanking plate was sufficient to fix it. The cause? I changed a side cooler to a down cooler on the GPU; meaning the ambient air was too hot. So that's what I'm getting at with temperature sensors, where they measure is important, but through-flow is equally important.

It's a subtle science. Certainly one I've not totally figured out yet.

I should not:
a. Read your posts.
b. Play with anything important
when it's 0200. I will only:
a. Not get it the first time, and end up doing weird things when I should have re-read what you (and other people) tell me.
b. Blow something up.
Virtual Travellervtraveller on April 18th, 2007 07:11 am (UTC)
ah - did you:

a. hear a 'crack' sound
b. smell plastic
c. see a small tee-pee plume of smoke
d. all of the above

I'm guessing as you can post it's not *that* bad. As I say, it's a strange science. What one would deem logical and sensible doesn't always pan-out the way you'd think.

Poke, sample, redefine, repeat.
