Air cooler suggestion? Read Description - Page 4

post #31 of 220
The reason you want a big heatsink is because of the way that thermodynamics works. Think of thermodynamic transfer as water flowing, in the sense that when water flows it flows from areas where water is to areas where water isn't, until there's an even level of water over the whole area. Temperature is the depth of the water (depth in a container), heat is the volume of the water. Also, imagine all containers are of a height so that when full, temperature is maximum for your CPU. In this analogy, all containers would be the same height but the radii of all of the cups vary.

A bigger heatsink is like a container with a bigger radius (and therefore area). When you pump heat into a heatsink (chunk of metal), it evenly distributes the temperature across the system. So it takes more heat to heat a larger heatsink to the same temperature a smaller heatsink would reach. A larger heatsink can take the same amount of heat and have less temperature. Think of a thin cup vs a really fat cup. You could pour the full thin cup into the fat cup and it only be a quarter full. In the same way, a really tiny heatsink (stock cooler, for example) would overTEMP your CPU at much lower heats than a larger heatsink. A larger heatsink will be cooler for the same heat absorption.

Another difference is that the more surface area you have the more of a chance for cooling there is. Plus, a bigger heatsink means a bigger fan which means more airflow across more surface area across more fins which means exponentially better cooling. Now, very efficient heat transfer (conductivity) is more important than heatsink mass. 100% perfect heat transfer isn't good transfer, it's 0% insulation. So any inefficiencies in heat transfer don't only hurt the heat transfer, but it insulates the CPU from cooling. So, where the CM Hyper 212 wins is that it is simply the best at conducting heat up and away from the CPU....not because it's the heaviest.

The Mine 2 nearly matches NH-D14 performance with two fans.

Scythe make some very good coolers. Mine 2 is one of them. thumb.gif

Am I the only one who thinks 56C isnt that hot?

You cant go wrong with a H100 thats my choice smile.gif

H100 is twice as loud, has a proven history of defective pumps, defective fan speed control, with owners getting 2 or even 3 RMA replacements and still having problems... And it has more moving parts to wear out... pumps do wear out.

Sorry, some of us are just simple folk and like simple cooling solutions. biggrin.gifthumb.gif

Well that wasn't the best sentence to put me off water cooling was it? biggrin.gif haha

But yeah I may just go with the Scythe Mine 2, it looks amazing and provided it can be installed horizontally. It is massive but looks easier to manage than my Xigmatek Thors hammer from some of the Youtube videos.

Also, bit concerned about the weight of it? Is this a problem because its very heavy?

I have never seen or been able to verify a case of these big heavy coolers damaging a motherboard. Well, I have heard of a couple of instances where someone dropped their case a couple of feet and did damage. biggrin.gif

One guy hauled his tower to and from work daily and eventually had some problems. rolleyes.gif

Nothing is unbreakable. I sure some people can do damage to a solid block of steel. rolleyes.gif

Edit: Naah, not the best sentence, but you got the message. wink.gif

The above case of guy hauling his to and from work was it broke when he had to slam on his brakes and it feell off the back seat... Didn't hook it's seatbelt properly I guess. biggrin.gif

Haha wow thats unlucky. I would probably buy a laptop than moving a giant case around with you biggrin.gif I keep my case where it is, I do have to drag it off 10cm high drop, but that isn't exactly big biggrin.gif

I take it most big coolers have good mounting brackets on the backplate to hold it properly. My Thors Hammer isn't terribly heavy, doesn't feel big anyway.

If I bought the Mine 2 I will more than likely just use the single fan otherwise it'll get a bit big with 3 fans and probably unnecessary (though that would look awesome biggrin.gif).

I may take out the side fan, don't think it does much except for direct the intake through the dust filter. So may just stick some dust filters on the side vent to help a tad biggrin.gif

I don't think I would ever go to water cooling, a lot of hassle and danger of the pump leaking. Besides I think air cooling looks a lot better in a case. Deciding whether to change all my LEDs to AC F12s to give a nice white looking case, or to keep an orangey white LED effect. Hmm decisions!

Thanks for the suggestion, the Scythe Mine 2 is only £27 on Amazon, that is cheap! it is thinner than my current and the horizontal design will definitely help!

Thanks again for helping to everyone biggrin.gif

I'm curious what's the difference is at the end. Make sure you test it before and after.
