Should I buy a ZALMAN CNPS7700-CU HSF for my new AMD 64 3000+ Venice/ DFI Lan Party NF4 Ultra-D?

I will be OCing the badboy as much as I can. But will I be just as well off with a less expensive HSF like the 7000 series?

Thanks!

IF you want the best for cooling, get a thermalright cooler (specifically the XP-90 or XP-120). Those Zalman coolers are more for silence than for very low temps (but they still are excelent heatsinks).

Was also thinking of the thermalright ones. Specifically the XP-90, but is there a big diff. b/w the XP-90 and the XP-90c? I know the C is heavier but is the cooling from having copper based heatsink that much better?

thx.

Sorry to burst the bubble but to make such blanket statements concerning "the best cooling" is bogus!!

The zalman as well as the thermalRight are all in the same league!!

Yet with that said--Im a zalman person so I would go zalman!!
I also might wait until the new Zalman comes out before making my decision!!
I have read reviews an all 3 of the above coolers for my money its Zalman all the way!!

Cool...

I bought the Zalamn 7700cu for $40 shipped. Best price I could find...

Ummmm... no. Xp-120 beats 7700cu by a solid 5-10*C with both <30dBA. And the higher airflow you go the more the xp pulls ahead.

I dont know. A Scythe SHOGUN is pretty cool. The if you still nee more bang then get one of those Delta 120mm fans. 0 Silence lol. But powerful cooling.

Did good to order the Zalman, you wont be disappointed, I assure you. Never used a thermalright cooler, so I cant say anything against them, but I can say something for zalman cooling, it excellent!

Zalman coolers are good because

- They come with a fan controller
- They're dead silent at 5V
- The flower design is impressive
- They cool other parts on the mobo

They haven't used the flower design for years. They are all funnels now... except the newest on which is a wind tunnel.

Well seems like a lot of people say Zalman is good. And I'm sure if I were to get an XP-90 or 120, it would be equal to the Zalman.

But I went w/ Zalman anyways...can't wait to install my new rig with it. I think what pushed me over to the Zalman one was the silent part of it. But can't the XP-90/120 work fanless which would lead to dead quietness?

Nope. Zalman CNPS7700Cu is superior to the XP-90 and the XP-120 because it does a far better job of cooling other components of the motherboard other then the CPU by the way it's designed.

That's Zalman's "ace in the hole". It's just as good with the CPU as Thermalright's coolers, but the 7700 series also cools the RAM, MOSFETs, and Northbridge.

Yup...it's had to beat the 7700Cu. No need to purchase a RAM cooler with may motherboards. Add the SLK3000B case with side vent duct and you have an awesome CPU cooler.

I find myself giving this "opinion" over and over again.

The thermal resistance of the Zalman 7700 is 0.19. The thermal resistance of the TR XP120 is 0.167. The thermal resistance of the TR90Cu is slightly lower than the thermal resistance of the regular XP90 -- which is somewhere between that of the XP120 and the CNPS-7700.

the lower the thermal resistance, the tighter the spread between idle and load temperature values, which is desirable.

The ThermalRight coolers weigh half as much as the Zalman 7700 even with heavier Delta or Panaflow fans, so less stress on the motherboard.

As for cooling other components, the XP120 (at least) does the job equally well, and it can be enhanced even more by ducting the CPU-fan intake over the motherboard with foam art board. Such ducting would also confine "warmed-up" air for swift and immediate exhaust through a rear-case exhaust fan, but the CNPS-7700 is so large that this sort of thing would be more difficult.

It's all a matter of trade-offs and accommodation, but the XP120 wins on CPU cooling and holds its own as far as cooling chipset, memory and other components.

You're going to have to wait for the CNPS-9500-LED. I don't rag on Zalman coolers -- I"ve found their VGA ZM80x coolers to be some of the most effective. But I had put my money on heatpipe cooling more than a year and a half ago, and the data vindicates my choices. So it will be worth watching for reviews which show measured thermal resistance numbers for the CNPS-9500. Even if it doesn't trump water-cooling, it may be worth the trouble replacing an XP120 with a CNPS-9500 if it proves itself with a thermal resistance that is maybe 5-hundredth or more lower than the XP120's.

agreed. it cooled my sempron pretty well at 2.4ghz. Its a very good heatsink when coupled with the right fan

What would you say about cooling a X2 4400+ oc'd @ 4800+ speeds. I was told the fanless Scythe. I am now considering the Zalman or the Xp-120, cash isn't really a factor. It's going to be in a P-180 case, what would you prefer?

go with the zalman, my buddy has one on his 3400+ im gonna have one one on my 3200+ in about 3 days, they are excellent coolers

i and my budy both have the 7700 ALCU, mainily because of the weight, it cools to witin 1-2C of teh all copper one
