Megahalems Rev. B vs. Newer High-end coolers... How does it stand up? - Page 4

post #31 of 35
Thread Starter 
I'm not really much of a noob, I just don't follow water cooling tech or terminology because I've never set up, or even thought about setting up, a system. I'm not really an avid overclocker, but rather someone who just wants to get the maximum safe performance out of my tech. For me this has always meant air rather than liquid because of the potential (at least in the past, not sure about now) for leaking or the system breaking down and suddenly you've got no way to cool the CPU. Maybe things have become good enough now not to have to worry about such things, but if I can get a good OC out of my air cooler, it's hard to beat its simplicity.

As for delidding, I have done similar things in the past, and I'm well aware of the risks, so I'll leave that on the table, but only if I can't get anything decent out of the CPU without it. After all, I might have gotten lucky and ended up with a processor with good TIM and a solid connection so I might not even need it.

Pretty much agree with the simplicity of air cooling, it just works and there is nothing to worry about. The AIO water cooling solutions just don't seem all that appealing to me and from what I can see they don't perform all that much better. Also the questionable build quality of them puts me off, anywhere from grinding/failing pumps to leaks to complete drainage of the liquid due to a hose popping off ruining your system. Now custom built water cooling is much more reliable and worry free as there are tons of options to the quality of parts you can build one with.

I'd still be a bit leery with a custom built system because you're still introducing a mechanical pump into the mix. Considering I spend between 3-10 hours on my computer every day, the running time of said pump is going to add up very quickly. In addition, a custom system adds up in cost pretty quickly as well... Not even worrying about all the extra bits and bobs and just going by most popular items on the frozencpu site quickly adds up to $300+.

I will just say this, I have never had my system shut down due to the CPU getting too hot until I went with liquid cooling. Even getting the so called best of the best for an AIO unit.

Indeed.
$300 is very conservative.
And if CPU is going under H2O than GPU should as well. Today's GPUs make more heat than CPU does. wink.gif

As XAslanX said the CLC are only marginally better than top air and definitely will not last as long as air. Most reviews comparing H2O to air are performed in cases with only the room ambient temperature used as a reference... which greatly handicaps the air coolers. They never monitor the temperature of air inside of case that is going into radiator or cooler... and that is the important temperature, not what the room temperature is.
  • H2O by design have radiator mounted either intaking or exhausting air which keeps heated exhaust from mixing with cooler intake air.
  • Air coolers don't have this advantage.
  • Resulting is air temp going into cooler is much higher on air cooler tests than on CLC tests... and every degree hotter the cooler intake temp is translates to a degree hotter the CPU is.

jump in to 3:40 for results

I think it's fair to assume all coolers have same intake air temp in above testing.
Silver Arrow SB-E is 1c warmer and less than half as loud as H100. Silver Arrow SB-E Extreme is 7c cooler and just as loud as H100.

What is the cooler intake air temp of Silver Arrow compared to H100 in this test? confused.gif
H100. . . . . . . . . 46.6c
SA SB-E Extreme .48.1c
http://www.vortez.net/articles_pages/noctua_nh_u14s_review,8.html

Silver Arrow SB-E Extreme is 1.5c warmer... but how much warmer is the air going into SA SB-E Extreme ???

How efficiently is 500R case removing hot exhaust without it mixing into case air assuring us that Silver Arrow SB-E Extreme is getting cool air like the H100 did?

500D case has
2x 120 43cfm & 1x 200 92cfm intakes for a total of 178cfm at 0.00mm H2O.. We can probably take 20% off that cfm for case grill, filter, HDD cage, etc. resistance leaving 142cfm intake airflow
1x 120 43cfm exhaust. doh.gif We can figure at least 10% off for grill resistance leaving us with 38.7cfm exhaust airflow.
Of course air leaks out unused vents too

Silver Arrow SB-E Extreme has 2x TY-143 (130cfm@2500rpm 1.89mm H2O@1300rpm) fans in series so very little loss to cooler resistance... 10% is probably more than actual loss leaving us with 117cfm airflow thru cooler...
  • 142cfm case intake
  • 38.7cfm case exhaust
  • 117cfm cooler airflow[ B]3 times what case's back exhaust fan moves[/B]. eek.gif
You think it's fair to assume SA SB-E's heated exhaust air is mixing with case air and raising the SA SB-E intake air temperature? I sure do. biggrin.gif
