X2 4800 - CPU Cooler

Post by boe » Fri Feb 03, 2006 2:26 pm

I'm building a new system. I'm probably building a 4800 x2 system. I'd like a very quiet system. I have a Zalman 7000 on my p4 2.8 and love it. What would you recommend for an x2 4800?

Thanks

If you want to blow the CPU air towards the exhaust fan, the Scythe Ninja is the best heatsink that lets you do that.

Have you checked this out? http://www.silentpcreview.com/article30-page1.html

My understanding is that as long as it's supposed to fit the socket type, and it clears all your mobo (and other) components, it'll work.

Right?

Thanks - That looks a lot like the one used in the Dell Dimension XPS - does anyone know if that is the one? The one in the Dell works well although I think the exhaust fan they chose is a little noisey.

Are there any special requirements for this one?

I have a ThermalRight SI-120 on my 4800. It may not be as good as the Ninja by a very small margin. But it is very light for it's cooling capacity and will fit almost any motheboard. This reduced my CPU temps compaired to the stock heat sink by 10C using a Yate Loon fan.

i have same qs, but am much the newbie. my 4800x2 is on the way with asus a8N32 deluxe mb, and corsair 3500 ram. office use without any gaming--maybe 90% low usage with 1-3 min bursts of medium to medium high usage through out day. wondering ur opinions:

1. will ninja clear this ram on MB.
2. our second choice would be thermalright si-120--presuming this would fit with the ram. would prefer to use thermalright without a fan (there's a 120mm rear case fan near it)--can this sort of system go cpu fanless with this sort of low usage system.

The Ninja will block the first ram slot when you use this memory. It's much taller then stock ram chips with a normal heatspreader.

Everyone recommends the ninja, and its great, I have one and couldn't be happier. However the SI120 is very close in performance, but also has the advantage of getting airflow over the heatsink part of the NB cooler. Theres that nice heatpipe cooler on the mobo that just brings up the heat near the cpu socket, however with the ninja there is little ariflwo around thesocket. So although the cpu is going to run very slightly cooler, the NB is going to be alot hotter. Anyways the point i wanted to make was the ninja is not far superior, and case layout and airflow should become the deciding factor when choosing.

txs very much for making that point about the a8n32.

i dunno - i have an A8N-SLI Premium (same NB cooling concept) and the rear fans pull enough air over the heatsink at the end of the heatpipe. you dont really need to consider this when deciding upon the CPU HSF unless your rear airflow is minimal

I too have the Asus A8N-SLI Premium, and with no CPU fan whatsoever, just a single undervolted exhaust fan, the motherboard was 38 C. With an undervolted intake fan, it went down to 36 C. And that was, again, with no CPU fan at all. So the heatpipe is situated quite well enough for the exhaust fan to take care of all cooling needs, and the intake fan probably helped directly cool the northbridge itself.

Of course this is just the BIOS motherboard temperature reading; for all I know, there may be other parts of the motherboard that aren't being cooled as well.

(I redid this post)

Actually I watching the senor's readings on my a8nslipremium and they make no sense, well at least the 'motherboard' reading does not. Full load I've seen it up to 60C however I just noticed that going from idle->fullload or other way around the mobo temp changes instantly. In one second the mobo temp goes from 33C to 49C.. that doesn't make any sense. First of all it couldn't change temps that fast, plus the fact hte 33C doesn't even make sense. The NB is too hot to touch even when idle, no way its 33C.

So I cannot say with any reasonable accuracy the temp of the NB but it is too hot for me to put my finger on for more than a second or 2. And when you just look at the design of the ninja it is not going to create airflow around the socket, something that is needed. I've build many watercooled systems and I never feel good with leaving no airflow around the socket. Asus puts these heatpipe coolers on the mobo but they're not meant to be passive. Asus makes those blowers because some airflow is needed. I mean the heatpipe is just going to move the heat around not make it go away.

And fine yes my computer is stable using a ninja but really it would still be stable with the si120 yet the NB would be 10C cooler.. doesn't seem like I'd be losing much.

I've yet to see the northbridge temp go past 45C, and i'm running a 4800+ with a fanless ninja and 2 fans pulling air out in the top compartment in a P180. And this was running 2xprime95 and rthdribl to get my comp nice and toasty.

The rear exhaust fan is all that is needed for removing the lingering air from around the heatpipe, though an intake fan does help cool the northbridge directly.

when you get the CPU, try the stock heatsink first; before buying a new cooler; it has 4 heatpipes, made outof copper, and performs nicely
