Hi there, my specs

Processor: Pentium D 830 (no OC)
HSF: Zalman 9500 w/AS5
Idle: 43C, Load: 65C+

Using 2 copies SP2004 both Stress CPU for 30 mins. Any Pentium D 830 owners out there I think my temps are too high ... thanks...

I never measured the stock HSF because main reason I got Zalman was cos the stock HSF was so freakin noisy I ripped it out and sent it to the bin...

But for sure I clean the cpu nicely before apply Arctic Silver 5 (as per website instruction). The worse thing is my D830 is brand new and I cannot do overnight video encodes like I used to

The very best part is, I had it at Idle: 35C, Load: 60C BEFORE I put in AS5 (using Zalman provided thermal paste).

For reference I also bought a tube of Coolermaster Nanofusion Thermal Paste and tested 2days, also IDLE: 42C, Load: 65C+

Going crazy oredi....

Couple of days ago I setup my rig to have 12cm intake fan, 12 cm exhaust fan
No change in temperatures... does that mean that the airflow is oredi sufficient?

In fact for the Intel Thermally Advantaged Chassis design (airguide on side panel and also vents above the PCI slots) maybe there is no advantage of intake fan except for cooling the HDD?

Anyway update my rig temps

vey99 / Pentium D 830 3.0GHz / Zalman CNPS9500 w/ AS5 / idle: 36C, load: 62C ambient 33C (aircon room)

Stock HSF cooling power is good but the NOISE... aargh like running generator in the room... of course if you turn up the speakers when blowing away Strogg its ok, but when doing work is very distracting.

Hyper6 higher temps than stock HSF? maybe the fan blowing towards PSU which cannot exhaust the heat fast enough....

Socket 478 HSF is not noisy (my Celeron 1.7 is quiet), but my celeron D HSF spin at 3300RPM darn noisy, and my previous Pentium D HSF also same. Maybe my ears fussy? .....hehe

You maybe right lah, my last two I din't assembly myself ... not good to be lazy ... if thats the case my "thanks" go out to Jayacom and Thundermatch...

630 is preshot right? Anyway rigmaster should attach screenie cos I am sure forummers wanna see (snapshot of his rig even better) how to have good cooling with stock hsf...


------
Yesterday installed a Coolermaster Hyper L3 HSF onto socket 775 pc. I bought it cos it use the std clip and no need to remove mainboard from case. But the pins are a little crappy and could not snap into place nicely. Always 3 legs fit, one more cannot "click" into place. Finally still had to remove mainboard...

Cooler: Coolermaster Hyper L3 low profile HSF
Temps: idle 42C @ 2800RPM but apparently can lower the speed to 1100RPM if use PWM for ultra-quiet operation but I dont think that is advisable cos the cooling power is not so good.
Pros: Low profile, quiet (good for small case)
Cons: Weak cooling power
------

I was studying various cooling, someone retrofit a bar fridge compressor onto the PC case, its about 5 inch in height. Crazy man. But the site goes on to tell that its really not practical cos the dampening you have to put in. Imagine your fridge sound/ air con outdoor unit sound. Or you could do something crazy like pipe it to an outdoor unit like split air con... hehe

Just stay away from Pentium D 830 *sob*. Those Procs with Thermal Rating 130W are the hottest ones...

Hehe I'm just worried about the temps during load... anyway I'm done with my Intel. Most guys here all AMD kaki, time to build an AMD rig after so long loyal to Intel...

There is the Waffer PAC but I never see it here yet (~USD 75)

Ya . . When I switch on my aircon my temps drop by 6 - 8 C. But my tenaga bill .. aaargh...

Still apparently it takes up 3x 5.25 drive bays in height, and the highest setting ("snow") is apparently quite noisy. Prolly switch it to "snow" mode when doing overnight encodes...

i agree but then i think some ppl oredi did cooling for everything else... nothing left to cool?

Last night I added 120mm fan to the front of my midtower at the 5.25" drive bays to exhaust cool air in (with A/C on). No temps change. So now running with only 1 case fan, rear (exhaust). My stupid case very hard to fit the fan at the front bottom due to its design...

The brand is HEC, model is 6A (from the website) its very standard casing with 180W true power. Anyway this is just a transitional casing, I am shopping for a desktop casing that is black, tall enough to fit my Zalman HSF. Budget is < 300 so this weekend will drop by at LYP with a ruler

Cool man I will check it out ya.

btw, my temps with no case fan, only 1 PSU fan and 1 Zalman:
Idle 45C, Load 80C and climbing its super silent but cannot pakai one might overheat anytime

I "achieved" 80C by disconnecting my case fan, and only the PSU fan and Zalman CNPS9500 running at 1400RPM with 2 copies of SP2004 running (small FFT).

Anyway I discover that this setup is perfect for use when A/C is on Iand I am surfing net and listening to MP3 (temps is 51C). When idle I can hear my clock ticking louder than my CPU...

The spacing between fins in the TT is quite close safe to say it needs a good cfm fan... but it looks cool and you got the freedom to stick whatever fan u want on it too

The dream 3 looks pretty standard HSF but the fan looks a little bulky. Theres a long debate on copper vs alum, but I still think copper would be better ... personally i'd get the TT and stick a nice silent fan on top, I think dream 3 is sort of a stock hsf replacement only... (since its thermal resistance is 0.4143)

C/W rating - Celcius/Watt. Lower is better.

I refer to this article when I bought my HSF (funny how mine wasnt in it hehehe but I also refer to newegg.com)

but I notice u oredi have Hyper48 how come change? or new rig?

I just read the site and it seems lower is better so I just use it as a rule lah... but got some calculation which kinda makes sense also ... end of the day you still choose the coolest looking one (Coolermaster beetle)...

Copper is can transfer heat quickly as you can see from aircon also , and since the HSF makers call it thermal resistance then menas the less is better

Like Vervain mention, and also hotly debated at Cu vs Al thread, I also think that best combo is Copper to conduct, AL fins to dissipate. Depend on how u use it lor, if you not OC and got good case exhaust I think your proc wont fry if the fan fail (for pure copper hsf). Anyway I set my emergency shutdown settings pretty low as protection also...

but the xdream is so small lah , enuf cooling power meh? I still think its a stock HSF replacement model rather than an enthusiast cooler.
