Drive and CPU Overheat Using CD Ripper

[IrishPub]

I'm using CD Ripper on a PC with a Quad Core 9550 processor and a Memorex 530L DVD/CD drive. When I rip CDs, the CPU overheat alarm sounds and the disc drive also gets very hot. (The CPU is not overclocked.)

I would try to slow down the disc drive, but in the Options for Ripping Speed, there is no choice available to select other than "Maximum." I'm using the Secure RIP setting (not Ultra Secure), and for Pass 2 to Limit Drive Speed, there is also no choice other than "Maximum." I've tried ripping with and without Multi-CPU checked, but it doesn't change the situation.

I really don't care if a rip takes 10 minutes or 20 minutes, I just don't want my system to overheat. How do I slow things down?

Re: Drive and CPU Overheat Using CD Ripper

DVD drives are able to get hot, they are designed to rip at x20-x40 speed, any slower and modern drives can produce errors.

The CPU overheating is another problem, on a normal system, you should be able to 100% the CPU (all 4 cores) for 24 hours and not have a problem, I can on all my systems. Also check that the system has not put the drives into PIO mode and they are in DMA mode.

Re: Drive and CPU Overheat Using CD Ripper

Thanks for your reply.

The drive speed reported by CD Ripper during the rips was 47X, which is the drive's maximum. I don't see anything in CD Ripper or the drive's driver properties in Device Manager to indicate whether it is in PIO or DMA mode. Where would I find that info?

On the CPU, I have run Music Converter with thousands of files batched up and all four processors running full out for hours without the CPU overheating. Only CD Ripper has caused an overheat. For most computing work, the CPU temp is between 40 and 50 degrees C. During ripping with CD Ripper, it gets up to 75 to 80 degrees. No other ripping software (Exact Audio Copy, Nero, etc.) I have ever used causes the CPU to get anywhere near that hot.

Re: Drive and CPU Overheat Using CD Ripper

It's a bit of a long shot, but....

Is it possible that the increased heat dissipation from the CD\DVD drive is pushing-up the internal temperature of the computer cabinet, enough to counter-attack efforts to cool the CPU, leading to a raised CPU core temperature?

Best regards,

Re: Drive and CPU Overheat Using CD Ripper

I think it's quite possible that the CD drive heat is increasing the internal case temperature to the point that the CPU fan can't cool the CPU enough. That's why I asked if there's a way to slow down the drive. The System and PWM temps do rise somewhat during ripping (although they do not overheat). Bear in mind that no drive-intensive application other than CD Ripper has ever caused this PC's CPU to overheat.

Have you tried changing the ripping speed in the CD ripper options?

Best regards,

Re: Drive and CPU Overheat Using CD Ripper

In CD Ripper options, I have no selection to choose other than "Maximum" for drive speed. Indeed, one of the things I'm trying to understand is why CD Ripper doesn't let me slow down the drive at all.

Try using the DSP effect CPU Throttle, which allows encoding to be slowed down.

I'll have to play around with the setting some more, but that looks like it will do the trick. It never occurred to me there might be a DSP Effect for CPU speed control. Thanks.

That link appears to be dead. But I did find other info on checking DMA vs. PIO. My CD ROM drive shows as running in "Ultra DMA mode 4" in Windows Vista.
