This is reaction on the orginal tread:
...about how to get VIA C3 CPU
With the big help of TheEagleCD (i realy appreciate your help, dear friend - YOU make it possible!), who send it me to Czech Republic, i was able to finish my dream and make the server machine noiseless. There are lots of pictures and hopefully funny and enough descriptive comments bellow them, so feel free to take a look what the hell i did:

The machine have got some pretty interesting behaviours, witch i will post there later. At this moment, at the machine running Memtest-86 v3 ( http://www.memtest.org/
), witch i find more overheating the CPU/machine that just a CPU burn (P6 or MMX tests at high priority still not match this one), and it with slight pause running from yesterday. From todays noon it running non-stop and as i stated into the orginal tread, i don't stop torturing the machine for exactly 3 days
If she can manage it, it's entierly stable. Up to now not a single memory error or a glitch happen, however the machine is overheating pretty hard
When i first yesterday put it all togeter, i hit 75 degrees with the CPU burn MMX/hi priority test (!) and 77 degrees with the Memtest (i run both for 30 min, Memtest later, and with CPU burn i use MBM5 (SpeedFan not working yet, waiting for beta to test) for just-in-time temp checking and the Memtest values are from bios-reboot
Well, 77 degrees is too hot even for me, a CPU-torturing geek, so i removed all the bay casings on the case to open its back. That cooled machine i leaved for night running and at the morning (about 9:30) are there 70 degrees.
But still not good.
So, i made a hole to the case, to allow the cold air to get in trough bays and get out just there - see pictures. Pre-tests showed up to 68 degrees temperatures, so we see, what temp are there after 3 days of burning
Now some more-interesting values. When i have there Tulation 1300 stock cooler, slowed to 1670RPM by Zalman FanMate, i got on CeleronII CPU (900Mhz, Vcore 1.75) 41 degrees in iddle and 54 on load. Average, for the slow RPM, suxxking AL cooler and small case with CPU just bellow the PSU, what are on side into the case (see pics)...
With VIA C3 (1200Mhz, Vcore 1.4) i got starting temperatures as low, as 24 degrees on CPU (bios) and 32 on chipset. When Win2k server booted, these are 32 degrees for CPU and 29 for chipset (chipset get lazy, seems
But the most weird thing is, how the CPU reacting to the CPU burn. All system, including friend and my watercooling machines, inlcuding my past machines, including brother AthlonXP aircooler and little sis Duron aircooled - every these machines react very quickly on the CPU burn. All raise their temps and in few minutes reaching the almost top temperature.
Not VIA. Either it's thanks to the ultra-low 18W of heat (don't P4 got almost 5 x more? http://www.tomshardware.com/cpu/20031230/index.html
- 84W for the 3.2Ghz version for those, who don't want to be bothered to read up to page 3
) or it's the huge passive cooling?
But i used exactly same cooler on the CeleronII once and on my Tualatin 1300 as well, and everytime it reacted the same way... (well, now W/O fan...)
And this bring me to to last thing - the cooler. For VIA passive cooling, Zalman made its CNPS6100Cu-Al low-cost version of CNPS6000.
However because even the CNPS6000 it's still not delivered yet, not to mention that the CNPS6100 is "yet to come", i used my older CNPS3100-Plus one.
As you can compare:
http://www.zalman.co.kr/english/product ... 00alcu.htm
...the 3100-Plus and the CNPS6100 is not such much diferent. Two facts. Heat dissipation area (the only one important thing in passive cooling) of 3100 is rated as 2000 square cm, where 6100 is rated as 1800-2200 square cm. Interesingly - 6000 and 6100 looking same for me - but the CNPS6000 is rated as 2600-2900 square cm
Anyway, my CNPS3100-Plus is all-cooper, onlike the CNPS6100Cu-Al, so i dediced to not waiting anymore for CNPS6100 and giving CNPS6000 it a try.
The relatively high temperatures are a bit weird for me. Either i have such badly overheating case (check the case on pictures), or i have no clue, how the cooler can passively cool the CPU into more extreme cases, that's the mine...
Also I'm up to discussion, whatever the "BeatTheHeat.wmv" animation showing that P3 crash 5 sec after removing heatsink (no dubt about it
) is real or is not it. Because given the temperatures with my Zalman into now relatively well-ventilated case (
rate my case mod, please
) and the fact this is the new core, witch should generating less heat (perhaps not, its 1.4V and the previous Ezra-T cores are 1.35, IIRC) I'm slightly start dubting about it.
Don't get me wrong, i still LOVE my VIA cpu, trully and deeply. I just don't think that it can make it W/O heatsing at all and the words from the anim "...your is cold as ice..." facing the 77 degrees (thats record, i never measured such high temperature on anything before) sound me now a bit weird.
So, either i did a pisspoor job, or have overheated room (about 17-18 celsius at nights and 20-22 on days - that's at least what i think it is
) or the anim claiming 24h+ running VIA C3 800Mhz Enzo-T core under full load (Q3 demo don't allow the CPU to breath, I'm sure about it) is fake.
Let me know, what do you think
