Liquid Cooling

Hi,

I would like to know if liquid cooling is better than fan cooling and if so
which of these two kit would you use to cool an AMD Phenom II 810 or better

Kit #1 : ProWater 850i from Thermaltake
Kit #2 : BigWater 760i from Thermaltake

Most liquid cooling kits require fans for the radiators. The
difference is in how much heat they can remove. Also, the liquid
systems may require more maintenance.

You don't need liquid cooling unless you're overclocking the CPU. Even
then, a good case and CPU cooler can work for reasonable overclocks.

I do not overclock an the case that I am using right now is a ThermalTake
Mozart TX, it is huge and has very good ventilation

If you don't overclock then there is no point in going to liquid cooling.

If your CPU temperature is a little high, I would suggest looking at an
after market heatsink and fan (HSF)... something like the Titan Fenrir
or the old, but still good, Arctic Cooling Freezer 7 Pro.

I have an Intel quad core (Q6600) overclocked by 40% on air cooling. My
CPU never gets over 55C even when loaded to 100% for hours at a time...
Of course good case airflow helps!

In general, liquid cooling is for extreme overclocking or cosmetics
only. A good HSF is a LOT cheaper and better cooling than most liquid
cooling kits anyway!

Even if my appartment is averaging 26C with about 60% humidity

Yes.

What is your CPU temp under those conditions? Which CPU?

My office is 27C now, and my Q9650 with Noctua NH-C12P cooler is
running at 46C per SpeedFan or 45-51C per CoreTemp at constant full
load on all 4 cores.

I use an AMD Phenon II 810 and it is idling at about 40 - 43C per core

And it reach close to 55C when I use FSX for awhile

55C is not a problem; the CPU is rated to 71C. You can easily run it
for a long time at 60C without harm.

You might be able to reduce it 4-6C with a good cooler. You can google
for reviews and comparisons of various models. I did that several
months ago and chose the Noctua when I bought the Q9650. My office has
been over 32C, and the CPU (same 95W TDP as your Phenom) did not go
above 63C at full load.

The reasons for water cooling are to enable extreme clocking of
overheating CPUs and to achieve silent cooling. If you dont have those
requirements, water will only bring you downsides.

Finding review the way you propose is impossible since I do not have Google

From waht I have seen, installing another fan would require that I drill
holes in the motheboard to fix those screws, is there any other fan that
will use what is already there on the motherboard to keep in place

Yes, even then... My office is currently about 25C (Humitidy makes no
difference to air cooling). My CPU cores are all about 32C idle and 55C
on full load.

You don't have Google? Could you please explain that? Do you not have
web access?

Many of the 3rd party HSFs come with fitting brackets for most of the
CPU mounts including AM2, AM3, 775 and i7 sockets. No drilling is
required. I beleive the Titan Fenrir is one such.

Humidity actually does make a difference. Convective heat transfer
increases with increasing humidity.

I find it hard to believe you can post on Usenet but do not have
Internet access via a web browser into which you can type
http://www.google.com ...

No drilling needed. Some (most) high-end coolers require you to remove
the motherboard and fix brackets to the underside to support the weight
of the cooler. However, they use the same holes as the stock cooler,
and come with adapters for the specific CPU socket. For example:

I do have web access, but Google is lock by ISP, since they are using Yahoo,
we can not use anything else but their search

What is HSF ?

An ISP that chooses which search engine you can use? I'd be looking for a
new ISP.

HSF= HeatSinkFan, your CPU cooler.

But the cooler that came with my CPU did not have any hole, it fitted rigth
on top of the CPU without the need of any holes, it just knd of fit there on
the CPU bracket

I just checked the images from the installation for the one that you just
sent me below, and there is need to drill, otherwise how else do the screws
goes trough the motherboard.

And I do not think that setup would fit on my CPU, it looks like it is twice
the size of the motherboard

What is your motherboard? Are there not 4 holes distributed around the
CPU socket, whether or not they are in use for the current cooler?

Zoom in on the picture of this Asus AMD motherboard. There are clearly
4 mounting holes around the CPU socket, currently filled with a plastic
spacer:
http://www.newegg.com/Product/ShowImage.aspx?CurImage=13-131-368-S03&ISList=13-131-368-S01,13-131-368-S02,13-131-368-S03,13-131-368-S04,13-131-368-S05&S7ImageFlag=1&Item=N82E16813131368&Depa=0&WaterMark=1&Description=ASUS M4A78-E ATX AMD Motherboard - Retail

Even the cheap Foxconn motherboard has them (the spacer is bright
yellow in this one):
http://www.newegg.com/Product/ShowImage.aspx?CurImage=13-186-165-S03&ISList=13-186-165-S01,13-186-165-S02,13-186-165-S03,13-186-165-S04,13-186-165-S05&S7ImageFlag=1&Item=N82E16813186165&Depa=0&WaterMark=1&Description=Foxconn A7GM-S 2.0 Micro ATX AMD Motherboard - Retail

Those mounting holes align perfectly with the illustrations in the
Noctua AM2 installation manual. Other coolers will be similar; find
one that will fit in your case.

With such little apparent knowledge/experience with even a simple CPU
heat sunk & fan assembly, I suggest you NOT attempt anything to do with
water cooling.

Then use Yahoo!!! What is the problem?!?

HSF == Heat Sink & Fan
