Silencing a 1090T X6..

samiam · Post by **samiam** » Wed May 05, 2010 12:09 pm

Not a total newbie for silencing.

I have silenced a E8400 and a 4850e using Scythe Ninjas.

My current machine is a:
1090T X6 AMD (6 Core 145w)
1 x Yate Loon Fan, with the voltage downgraded.
1 x Scythe Ninja Mini (have a non-mini, but the fitting is way too tight to get on. Don't wanna risk destroying the cpu by forcing the heatsink on)
1 x Scythe Ninja Mini Fan. <-- The problem with my current setup.
(Without the fan, cpu temp goes from 25d -> 50d celcius.. bad..)

I used to run:
E8400 C2d
1 x Scythe Ninja Rev B
1 x Yate Loon case fan

I want to get the current machine to the same setup as the E8400, i.e. I guess I need a BIG heatsink.

My case is an Antec 300.

What heatsink should I buy? I want to pull the trigger tonight and get it by Friday if possible..

Thanks guys.

First:Welcome to SPCR!

If you look here:
http://www.xbitlabs.com/articles/cpu/di ... html#sect0

You will see that a AMD x6 will consume just about the same amount of power as a amd x4 965BE, and about 20 watt less than a i7 920.

And if you look here:
http://www.bit-tech.net/hardware/cpus/2 ... e-i3-530/4

You can see that 98 Watt more is used when going from a e8400 to 965. Thus, your new heatsink has to deal with 100 watt more heat than a e8400! No wonder your minja couldnt handle it

SPCR also has tested cooling a i7 920:
http://www.silentpcreview.com/article1018-page3.html

With a nexus at 7v, a megahalems can handle it, and if you undervolt the CPU a bit, a slower fan speed might work as well.
Your CPU consumes 20 watt less, but it still would be hard to cool this passsively, so you could move the yate-loon (<700 rpm hopefully) to the heatsink, where the airflow would be of better use.

I'd buy a megahalems, if you sacrifice enough performance (with Minja and a nice 2000 RPM fan you could probably get to >3.4 Ghz, you'll have to turn sth like that down for passive) it will surely work.

Keep us updated

Happy to pull the trigger, but the Mega doesn't fit AMD 2+/3?

Any idea?

you can get the AM2/3 adapter kit.

You could consider leaving the Mini Ninja on it and strap a 100mm thin (15mm) scythe fan to it which will cool it more effectively and quieter than the stock 80mm fan. The 2000 RPM thin version Â£5 puts out less air than the stock 80mm fan at 12v but it'll make less noise and if you were undervolting the stock fan due to noise this would be a way to get the airflow back up. If you get one of the normal thickness 100mm fans or a 92mm fan like the SFF92B at about Â£8 you could increase the airflow and still get a better noise quality than the stock 80mm fan.

Another cheap option would be the Xigmatek HDT-S1283 about Â£20. Use the included fan or your favorite 120mm fan can be added.

If the aim is to silence this CPU then given that it is in the Core i7 bracket in terms of both power and performance I would say that it needs a substantial cooler. It has a turbo mode for instance, and I don't see it being cooled either adequately or quietly with a cooler intended for a far lower power processor.

From Scythe I would look at Mugen 2, or the recently introduced Yasya. There are UK sources for the Yasya including this one http://www.scan.co.uk/Product.aspx?WebP ... ce=froogle. The Yasya is interesting because it includes a PWM fan that can be set to Low or High rpm ranges. This would fit in with a system that has features that make it cool and quiet at idle, but under stress for example gaming will consume a fair amount of power and generate significant heat.

Lodestar:

Ordered the Yasya. It comes tomorrow, i'll take a few snaps once it's installed and post back here with my results. /fingerscrossed

Cheers guys.

Ok, got the Yasya and installed it. It's very easy to install compared with the old Ninjas. The clips are significantly better, there's no denying it.

Some simple comparisons:

Single yate loon case fan with the cpu heatsink, cpu idling.

Scythe Ninja Mini: 60+ degrees C
Scythe Yasya: 32 degrees C

Full load, after 10 minutes (Prime95):

Scythe Ninja Mini: Computer shutdown

Scythe Yasya: 65 degrees C

That's with a single Yate Loon at 700ish RPM.

Incidentally, the Yasya fan that comes with it, even on the slowest setting is far too audible for my taste.

Right now i'm considering a push-pull setup with 2 x Yate Loons. Both at 700ish RPM. However, for now i'm going to stick with the single case fan and no cpu fan.

I'll decide after 24 hours when I look at average temps + system stability.

Will post pics tomorrow

I just noticed this post:

Grand Kama Cross. Yes I just said that, but if anyone looks using this one, they will wonder.

Gaming for 2 hours it got up to 51 C, idles at 31 C. Room is quite warm compared to most, like 75 Degrees F.

I hate celsius, it has not fine movement between the degrees.

75F is about 24C. It's certainly possible that your CPU is idling at 31C but you might like to try something like the free CPUID HWMonitor from here http://www.cpuid.com/softwares/hwmonitor.html to see what other information it is giving you.
