Customer Review: The most awesome CPU cooler you can buy, period.
Summary: 5 Stars
OK,
I have a massive workstation, custom-built Quad Core 2.6GHz with 4 GBs of DDR2 RAM and two super ATI Radeon 2900XTs in Crossfire with quad-pathed 512 MB GDDR3 each (which I tweak into overdrive on occasion, but usually, even when playing Day of Defeat in HD, its at default clocks because there is enough video horsepower).
I had a regular, comes with the processor Aluminum fins with the fan. Those A fins are tiny and tightly packed, often clogging up with dust.
~ CPU Temp during normal desktop idle - 50C
~ during normal desktop use - 56-60C (the high end with Excel using all
four cores running calculations)
~ during gaming in HD - 66C
I come to Amazon to shop for an alternative. Because even with Arctic Silver compound (which has excellent thermal transfer) I would be near the boiling point.
Automatic thermal protection shutdown was enabled. Good part - saved the Quad Core. Bad part - trashed my iPhone updated in progess and had to restore it and re-download all the apps today)
Zalman arrives just in time (picked slow shipping, cheaper). I open the box and right away I can tell this is one of the best products I have ever purchased (next to the new Sony 52 inch HDTV 240Hz - {insert grunt here}).
This thing is not mil-spec, its like NASA grade. 100% pure copper and it is enormous!! Make absolutely sure you have the case space to install this monster of a cooler. Wow, simple yet perfectly designed. The giant fins and the radius of the space the fins are perfect to displace the heat. It follows the First Law of Thermodynamics to a tee.
Why is this cooler two or three times the price of others?!? The manufacture is dealing with historically high copper prices, so costs have gone way up. But copper is the perfect metal to use, so, if you really want a good thermodynamic response - use pure copper.
Now, installation is NOT for beginners. WARNING!! Go back and re-read that first part. You MUST install a back grid under the motherboard where the CPU mount is located. This requires deassembly of the entire computer to perform with most cases. This unit is a heavy object in the computer and it must be firmly pressed to the top of the CPU cover to press out the thermal grease and create a good thermal gateway. If you need help, go to a shop or something and have some install it for you. It is well worth the $50 bucks. I did it myself (I am a pro geek).
CPU Temps with the massive Zalman installed!!
Idle desktop - 30C which is EXCELLENT the S.M.A.R.T monitor says the temp is actually too low, funny
Normal ops desktop - 36-38C
With game in HD running (along with Rhapshody, iTunes, Outlook PTRG and Y!IM running on the second desktop) - 40C with all GREEN in the S.M.A.R.T. monitor with the fan running at ~2446RPM.
If you have a tower system with high end CPUs and video cards - BUY THIS CPU COOLER! Can't go wrong (as long as it fits your case!)
