replacing hs/fan finally

Christo

ok i have left this for a while, this my first build i have learnt alot

like dont rely on stock hs/fans for nice cool temperatures

I have a few new fans in mind

Akasa AK-827
31.37CFM/2500 RPM
80 mm fan
http://www.akasa.co.uk/spec/coolers/spec_ak_827_bl.htm

Coolermaster Vortex Dream 7 CPU Cooler
no CFM rating/3000RPM
http://www.coolermaster.com/index.p...ial=ACC-L72&other_title=ACC-L72Vortex Dream 7

Akasa AK-825
max 45.4CFM/MAX 4000RPM
http://www.akasa.co.uk/spec/coolers/spec_ak_825.htm

i can see from MSI core centre that my current fan is spinning at just over
4000 RPM

now these fans above appeear only to have lower RPM's does this matter, i
dont think my current STOCK AMD fan is 80mm will that make much difference?

as to thermal grease/paste i dread this for some reason, i would idealy like
a hs/fan with pre applied grease/paste however if need be i will apply if
someone can give me any instructions, i have been told here countless times
previously and people probably are getting fed up but pwease..... hehe

do i spread it over the CPU core only?

or do i pread it over the entire base of the heatsink? or just the area of
the heatsink that comes into contact with the core?

if anyone has any other socket A hs/fans for me to take a peek at i will

i have asked this before and am no science eek or anything but metholated
spirits... will clean processor core? thats white spirit... the stuff you
use to get paint off anything, the highly flamable stuff that stinks!

that will do yeah?

The akasa coolers aren't really optimal because they only
have a little (thin) copper plate on the bottom. Even so,
if they're priced right they should be a fair value.

There is no need for high RPM provided the (metal portion
of) heatsink is good. An Athlon XP @ 2.5GHz can stay cool
enough from a 2500 RPM fan on a good 'sink, more or less
depending on case ventilation and ambient temp.

An 80 x 25mm fan will make a difference. It will move more
air, and/or same air with lower noise, and a 'sink big
enough to accomodate one properly (if 'sink doesn't just get
bigger at the top to accomodate mounting the fan) will
typically have larger surface area- removes more heat per
each CFM the fan moves.
as to thermal grease/paste i dread this for some reason, i would idealy like
a hs/fan with pre applied grease/paste however if need be i will apply if

It's quite simple, just thoroughly remove the original
interface (material) and apply a paper-thin layer.

If the heatsink base is rough or uneven, lap it first. It
need not end up a mirror finish, but if you can run your
fingernail edge across it and feel resistance, it would
benefit to lap it (more?).
do i spread it over the CPU core only?

Yes, very thinly on the core, a blob of grease the size of a
grain of rice is plenty... then unless the compound is dried
out, too thick, after putting the heatsink on the pressure
and heat of powering system on/off a few times will squeeze
out excess compound. Don't expect absolute lowest temp
immediately, it may take a few days to drop the last 2-3
degrees, shorter with thinner compound or longer with thick.
or do i pread it over the entire base of the heatsink? or just the area of
the heatsink that comes into contact with the core?

No, it is not necessary to put it on the heatsink.

I prefer the Thermalrights, they significantly better than
even what was once considred a very good 'sink, a Pal8045.
Granted, if one isn't overclocking the difference may not
matter, may 'sinks can be sufficient in moderate environment
at stock speed/voltage.

Thermaltake Silent Boost is another good ready-made
combination 'sink-fan, particularly because of the Panaflo
fan it comes with.

yes, though anything with "petroleum solvent" in it should
suffice. Even WD40 or gasoline. Low-odor solvents include
adhesive-cleaning targeted products like "Goo Gone". These
are only needed for the gummy solid pad types, and not all
of them... some will clean off with regular rubbing alcohol.
Regular grease will wipe off with a dry paper towel, no
solvent needed. Ideally one who wants to use a different
interface (grease) will clean if off the 'sink before it's
ever placed on the CPU so there's nothing to clean off of
the CPU... and on some Intel CPUs or AMD with heat-spreader,
it can be much more difficult to remove a heatsink stuck
onto the CPU heat spreader by a thermal phase-change pad.

Mainly just take your time, don't use too much compound, and
check CPU temp immediately after first powering on the
system.

thanks again knoy sound advice, i think i will be going for the coolermaster
vortex dream or maybe the akasa ak-825

cheers

My favorite hs/fan is the Thermaltake TR2-M1 (mentioned prior as the Tr2tt).
http://www.newegg.com/app/ViewProductDesc.asp?description=35-106-602&depa=0

For $10 it can't be beat. I've used probably 20 of them in various builds -
some overclocking, some not. All of the ones you've identified are good. I
just can't see spending an extra penny if it's not justified. And I don't
think it is in your case. That's just my opinion. Please, do what you
want.

As for your reservations about applying the thermal paste - relax! Have
some fun with it. It's really easy, and IMO preferable to using the big
glob of goop that usually comes pre-applied. I've done it literally
hundreds of times, and I've learned that the biggest mistake people make is
thinking it should go on like cake icing. The thing to bear in mind is the
real purpose of the grease is to create contact points in the microscopic
grooves and imperfections found on the bottom of the heatsink (and to some
degree the top of the cpu). While it looks like it to our eyes, the bottom
of the heatsink is not perfectly flat. There are many little grooves and
ditches left from the manufacturing process. Without thermal paste, the cpu
will not make contact at all those little grooves. Air will exist there,
which does not provide good heat transfer. The thermal paste fills in those
tiny gaps. So imagine how little paste you really need to fill up those
little grooves. Not very much! There is no reason to slather the paste on
there like icing a cake. Excess just gets squeezed out the sides anyway
when the pressure of the heatsink's retention clips is applied to the cpu.
Squirt! Simply rub a tiny bit of paste on the cpu chip, then a little more
to the center of the bottom of the heatsink. People have debated all sorts
of scientific methods to apply the stuff, but a very light touch with the
tip of your finger works just fine. It ain't rocket science, although many
people swear it is. IMO, most of those people don't build a lot of
computers, either. They're just going by some extreme method they read on a
website.

Try it. Re-post here if you have any questions or need more help.
