i was woner is the coolmaster cpu fan any good look lie a big jet, not the ome type.http://www.svc.com/acb-v83-u2.html


i need one for a 939 opty 165 with out breaking the bank, also what a good emp for core after 15 minute of othros?

Well, I've never used that before, but I'm not sure I would go with that one. It looks like that is basically just a regular block heatsink where the fan pulls the air around/under the heatsink and blows it towards the case exhaust fan. In my experience, when using a non-heatpipe heatsink, the most optimal way to cool the HS is to blow air on the heatsink (hence why regular block heatsinks have fans blowing on them and not away from them). However, when using a heatsink that has heatpipes (which efficiently draw heat from the CPU and conduct it to a larger heatsink, farther from the CPU for more efficient cooling), then blowing air across the HS is optimal (as opposed to blowing it on/toward the CPU). That's my 2-cents. If it were me, I wouldn't bother with this one, and you might as well spend the extra money and get a decent cooler--I really like the Zalman CNPS9500, with the large circular heatsink. I think you can get them for around $40, and they're well worth the price. I have one on my 4400+ S939, and it runs at about 28C idle and about 43C full load with Orthos.

Regarding temps, as long as you're under 60C on full load (orthos), the CPU is safe. However, most people use 55C as the rule of thumb.

Note--you can find better HSF's than the Zalman 9500, I was just using it as an example--I know that HSF you linked was only $10, but I highly doubt it will do anything to cool your CPU more than a stock cooler.

Do you know if your stock cooler is the Opteron 4-heat-pipe cooler, or just the regular AMD block heatsink? There would be four pipes that curl around the heat sink if so. If you have that, then the HSF you linked would definitely be a downgrade. If you have just the regular AMD block HSF, then go with something other than the one you linked.

stay away from that cooler! lol, its rubbish......i doubt it will cool any better than the stock AMD.

good cooling, and wont break the bank ;
Artic Cooling Freezer 64Pro $24
(for further temp reduction, lap it and stick on a silverstone FM92 fan)

I know we've all gotta start somewhere, but if this guy is asking about the previously mentioned HSF, do you think they'll even be interested in lapping? Though your solution pwns mine...

how long should i run orthos to get a good tep reading? 15mins?
post #7 of 11
15 mins is a fair amount of time to get a good estimate of what your max temps will be

but coretemp should 2 readings core 0 and core 1, do i go with the higher one?

It's for Socket A and Socket 370. Relatively old systems. (Athlon XP/P3)

It actually isn't that bad of a cooler. If you just look at the CFM rating, then it looks like crap. But the reason for the low CFM is the type of fan that it uses. The fan creates lots of air pressure and therefore keeps the temperatures down. The Cooler Master Aero 7+ has a similar design with a different fan, although they are actually quite similar.

As for the Jet 7, it's really heavy and the LEDs can get annoying (although they're fine by me)

So what is your budget? If you are willing to spend about $40, you can get the Scythe Ninja which is at a very good price ATM.

The Cooler Master Hyper TX is also very good for the price, with a price of $30.

I do hope that helps you. What is the max price you are willing to spend?
