awful temps:Volcano 9:lots of fans:HELP!!!

HI,

I am running a XP2100+ with no overclock, a volcano 9 and
5x case fans(1x80mm intake, 1x60mm intake, 2x80mm SFII exhaust, 1x120mm sunon exhaust).

Temperature in my room is about 18-20C, case is about 22-25C and CPU is never below 40C idle and 54-56C full load. Why are the temps so bad, this is zero improvement over the normal AMD cooler with the same case fans!! I have checked and rechecked how the V9 is seated and its fine!!!

Any help or suggestio9ns would be great, just don't say "get a SLK 700/800/900"

Thanks

Ttuser

 

have you tried the different speed settings?

 

All the SFIIs (inc. the one on the V9) are set at 4500rpm which is nearly full speed. Right now as I type this it is a stupid 48C

 

Its the Volcano 9 mate I've got it cooling my 2000+ palmino and idle i get 53 C. It absolutly crap and really noisey too its going for a Zalman

 

Uninstall MBM, it's the best thing I ever did (seriously), I can sit with my PC silent (80mm CPU fan running at less than 7V on an alpha PAL8045) and not worry about my temperatures, the only time I worry is when my pc crashes

Then I check temperatures in BIOS immediately afterwards, I'm sitting here with over 2 weeks uptime on a Tbird 1333 @ 1600 Mhz

 

fair point mate
i mean, who needs to keep a £55 processor for ever anyway?

 

Re cooling:
o If you have exhaust fan holes, fill them first
---- particularly fill any hole near the CPU

o CPU coolers are invariably impingement type
---- fan blows air at a plate with fins sticking out of it
---- this is noisy & less efficient than a "blow-thro" cooler
---- like Zalman flower or the Xeon windtunnel coolers
o Impingement creates a more insidious problem
---- hot air recirculation can be as high as 70%
---- which requires more cfm to compensate, so more noise

So choosing a blow-thro cooler over impingement can help,
it tends to get air further away & reduce recirculation.

However, recirculation will still occur if hot air remains in the case.
This is why cooling is system level, not just component level.

If you can fit a case exhaust fan near the CPU cooler - ideal.
This is typically done via a fan hole above the m/b I/O plate.
This gets the hot air out of the case, vs recirculating it.

The same idea is done by having the PSU intake near the CPU
cooler, but that is a cheap solution relying on the PSU fan to
cool the face re 2 fans costing more than 1 re profit margin.


Intake fans merely act serially to exhaust fans
o Cooling cfm is not additive, it merely gets closer to free air figs
o So ensuring you have sufficient exhaust fans helps

Another way of improving CPU cooling is to:
o Place a fan near to the CPU cooler in the side of the case
o This can be set to intake to blow cool air at the CPU fan
---- or in another position set to exhaust hot air from the CPU

Intake c/sectional area resistance is a problem on most cases:
o Hole perforation grills on intake are the worst
---- free-air space can be as little as 35%
o Perforated grill are a little better but only slightly
---- they can be 45%
o A proper wire grill or nothing at all is the best solution
---- this gives a figure of 89-93%

Noise level can also be reduced by migrating up the design chain.

You don't need a lot of cfm to cool a PC or CPUs:
o 300cfm will cool 1500W
o 30cfm will cool 150W

Most CPUs are below 80W, and the contents of even dual CPU
PCs are below 300W usually - so it's not cfm but how it is used.

Thanks guys,

I put a 92mm intake in the window pointing directly at the HS/F this has lowered temps by 2/3C but I think the Volcano 9 is the real issue.
I am only a poor school kid so a £55 processor needs to last for a while with me. I am currently saving up for an ABIT KT400 board so I can overclock the processor, my current board is the apallingly crap K7S5A. Maybe next on my buy list after the motherboard will be a nice skived fin all Cu heatsink...

Anyway thanks again,

Ttuser

 

Your temperatures seem okay I think. Won't really do your CPU any harm running at that temperature. You say you aren't overclocking, so it should be fine.

 

get a decent cooler

like a slk 900 with a 92 mm fan or evan a delta if u can stand the noise .

end of the day have u tryed to reseat ur cpu

wot thermal paste u using


edit = seen u have reseated it a few times erm .

well ... my m8s got a volcano and hes gettin about 50 under loads ..

remember its summer :O

my slk 900 is about 36c under load in the winter

now its a massive 47c
