Best Socket 939 heatsink/fan for K8N Neo4 platinum/SLI

[Guest]

I'm looking to buy a MS K8N Neo4 Platinum/SLI Motherboard and I trying to
find out what is the best heatsink/fan for a socket 939 motherboard for
$50.00 or less. I migtht be overclocking a AMD Athlon 64 3500+ (Winchester)
core.. Please give me you opinions on what to buy and look for. Your prompt
replies will be appreciated.

Thank You

The stock AMD heatsinks are very good these days - they're perfectly capable
of cooling an overvolted CPU.

If you *really* want to change it, then choose a

I agree. And at NewEgg, you can often get the boxed processor at the
same price (or even cheaper!) than the OEM processor. When there is a
price differential it's usually < $20, which is a good price for a
quality HS/F.

The retail-box fan is a bit on the noisy side when running full tilt,
but I have the fan control option set in the bios of my K8N Neo2 to
maintain the temps at 50 or below, and my fan speed rarely gets above
2500 rpm.

Very true. Have a go with the stock cooling, and see what temps you get
and if it's not too noisy for you.

The retail AMD 'sink is sufficient but it's not a $20-class
'sink if you find sales on aftermarket 'sinks. For example
this one has been at lower $20 sale price in the past and
far outclasses the AMD 'sink, would do even better with a
board having fan speed control.

When I looked on NewEgg yesterday, retail boxed processors were
selling for *less* than OEM processors. So in that case, they're
giving you the heatsink/fan for free.... or paying you to take it,
whichever you prefer.

You have to look very carefully at the CPU revision level. For example, even
for the same AMD64 3500+, the brand new Venice is more expensive than the
Winchester (both 90 nm), which is more than the Newcastle (130 nm).

But if the prices are close, always take the retail ones, because the
warranty is 3 years from AMD, and the OEM warranty (from the retailer) is
usually much less, sometimes only 30 days.

IF they were the same CPU core, that really is a good deal,
but also atypical as they usually are more expensive... just
seems like sometimes Newegg's large size means some prices
get updated before others and when you see a deal you have
to jump on it- might be different the next day.

Very true. Have a go with the stock cooling, and see what temps you get
and if it's not too noisy for you.

Even if it is too noisy, I would keep the heatsink and simply replace
the 70mm fan that came boxed with your prozessor with a more powerful
and much quieter 80mm fan using a fan adapter. The bigger fan can rotate
slower and more quiet while maintaining an even better air-throughput.

This does not only improve noise-levels *a lot* but also saves cost
(compared to buying a new heatsink with fan).

heck - why not a 70mm to 120mm adapter ;-)

Because the adapter causes quite diminishing returns.
IMO, the best solution wouldn't even be to use an adapter at
all, rather drilling 4 x ~ 4mm holes in th corners of the
'sink then strapping on a 80-92 x 25mm fan with thick solid
strand copper wire or nylon ties.

The problem with adapters is that they put the fan further
from the 'sink. This creates a larger volume of air the fan
has to maintain pressure on before it's expelled out of the
'sink, and these fans just aren't good at maintaining much
pressure. For optimal results the fan should always be as
close to the fins as reasonable- a few mm away from the
blade edges may help reduce some turbulent noise but much
further and the flow rate drops a lot.
