1) Look what Frostytech uses for cooler testing. No, it is not a CPU. Frostytech tests how good these coolers cool a piece of copper ([email protected]
for AMD and [email protected]
&150W for Intel). Sorry, but in my eyes that is not a relevant test. It tests the contact area of a cooler and heat transfer of it - but not how well it cools what it is built for - CPUs. You can't put a 125W thermal load on 38x38mm area and expect it to behave like a normal CPU does. Take a i3 530 for example :http://www.mobilewhack.com/wp-content/p ... corei5.jpg
Big area is a GPU, small area is the CPU. This is connected to the IHS. Will be the thermal load same at the whole IHS? Of course not. This invalidates their results. It is possible that their results are consistent with other testing sites, but they are not testing CPUs, they are not doing real world tests. It is more about what is under the IHS than about the socket. Core i5 750 will have a completely different thermal signature on IHS than Core i3 530, due the different position of the components inside - while both having same socket.
I don't call Frostytech stupid, i say they say many stupid things. They are also irrelevant in case of CPU cooling. They are good at copper cooling tests tho. If the tests are consistent with CPU cooling tests, it's their luck, but again - they are not testing CPU cooling. They test copper cooling.
2) In case of Core 2's, Xigmatek 1283 (with 3 direct touch heat pipes) was better than Xigmatek 1284 (with 4 heat pipes). Why ? Because 3 heatpipes made more contact with CPU than 4 heat pipes. Look at reviews where they review both of them, 1283 consistently beats 1284. It is not my statement, not my review - there are dozens of them. 1284 can beat 1283 only if all heatpipes make contact - which can be case of Socket 1366 CPU's, but not the smaller ones.
There are 2 things which differentiate the direct touch coolers :
a) surface quality - this is where many of direct touch coolers fail, if the surface is not perfect then you waste lot of potential with thermal compound which needs to be used to have any contact at all.
b) useless heatpipes - 4 heatpipe direct touch coolers work only with bigger contact area, which needs to have even thermal load - and even with i7, you have problems achieving that (look how the CPU looks bellow the IHS). For anything smaller, 2 of 4 heatpipes make less than ideal contact with IHS, making them perform well bellow their potential. That is why direct touch is not a holly grail of CPU cooling - because not all your heatpipes don't make contact.
Long story short, there is just a very, very small percentage of use cases where 4 heatpipes make sense for direct touch coolers, thus limiting their best performance to the performance of 3 heatpipes for majority of use cases, which means they are not good for Socket 1155 either (surface area of IHS is not big enough).
PS: I'm not all knowing, but there are simply some things which makes Frostytech pointless - not using CPU for CPU cooler testing, stating that stock Intel cooler is silent,... There are better sites, better reviews for CPU coolers than Frostytech. You are writing on forums of one of them
