Edited - The woes of the addicted OCer.

....edit - beware playing too much with your hsf, I managed to chip several pieces off my duron's edge bumping my hsf around. It also managed to gouge a chunk of the copper out of the bottom of my hsf so I am gonna have to do a little lapping to get it back down, that might be the cause of my instability, but ordered a new processor and shim (wish they came with one), so all the below posts are mute right now .......



First off, was probably my fault I had the 3C in the first place, but am learning as I go. If you look at my rig you can see im overclocking a Duron 600 to 904 right now, was higher but opted for higher fsb over speed. Besides the point.

Started off moding my case when I first got it. Enlight 7237
1)Drilled out the front panel holes with 5/16's bit.
2)Cut fan guard off the front panel(stamped metal one).
3)Replaced front with antec.
4)Installed antec in back blowing out.
5)Installed Enermax 330 with additional fan sucking air right over the CPU.

With these mods, I was happy. Not jumping for joy. Full load 45C
I figured this wasn't too bad. (Got OC habit - now am addicted)

Next mod was compromise, cuz I don't own a dremel nor do I have a hole saw and my wife has purse closed to me for a while.

6)Took cheap case fan that was included and installed in my top 2 5.25 bays and made shroud outta cardboard and electrical tape. (Told ya I was addicted).

With this mod was more happy, still not jumping for joy. Full load 41C.

Tonight am bored and wanna play. Makes shroud outta cardboard and electrical tape, (again yes I know addicted and bored). This shroud is a little different than most. I make it to fit tight over my delta fan on my Alpha PAL6035 (reversed to blow air on heatsink, not suck it away) and then it comes out and straight down to holes on side of case.

Getting happier, still not gonna jump for joy till thing becomes a water cooler and shuts up, but one other small benefit my delta fan is a little quieter with the shroud on. Full Load temp is now down to 37C. My system temp is also down by 2C.

Wondering what I can do next for almost free.

* edited - took case side off and watched the temp on my cpu drop to 34C still running RC5 and I felt my hsf and it was cool to the touch *

Happy Bump. Still playing and I used a little more tape to tighten the fit to the fan to stop some rattling that had started and its down even more (35C full load), what I think is so great is now I only have a 7C difference in system temp and CPU temp at full load. My celery 366a @ 550 ran hotter.

Anyone else out there getting similar reading?

IF you're accurately measuring case temp drop, then your gain is half tru, and half "faking out the socket-thermsitor". A 2C Drop in case temp will not result in a magical 4C drop in CPU temp.

Well on a continued happy note. The added cooling the shroud provided has let me run my processor up to 952 (136 * 7) with all the same memory settings I was getting at 904. And its Prime95 torture test stable. Going to let it run for a few days before I change my Rig settings again, just to make sure it goes through all my ambients that my house does.

To MikeWarrior,
I can only go by what my thermistor's read, the one under the socket and the one on the mobo. Don't have any other equip, wish I did. But I am going by what it use to read til now. When I was playing with my fans directions, I've had it running as high as 48C full load. I do have that annoying 38cfm delta fan on my hsf and 3 case fans plus the 92 and 80 mm on the enermax. The only thing the shroud really did was suck the cold air from the bottom of the case where one fan was blowing it in and not allow the delta fan to draw the warm air it was putting off back into the hsf and building heat.
All I can really go by is it is allowing me better performance than before.
