I have an ID-Cooling IS-VC45 (nickel-plated copper vapor chamber with aluminum fins) with a Noctua NF-A9x14 (the ID-Cooling fan that comes with the IS-VC45 works, but is quite noisy), and I must say that it works exceptionally. It is a little pricey at >US$60, but I would put it up there with any of those coolers less than 45mm height as far as performance (acoustics and thermals) goes.
Ahah I noticed I inspired some people with my S4 mini experience with ID cooling IS-VC45+noctua nf-a9x14 on core i7 6700K stock undervolt -0.1v..
I can just confirm its cooling capabilities...
I'll extend my experience on S4 mini with my experience on my last node 202 setup.
1st setup :
NFC S4 min #44 core i7 6700K + R9 nano..
By just undervolting core i7 6700K by -0.10V I managed to get a stable core i7 6700 stock clock in NFC S4 mini
On OCCT I managed to get around 80°C on cores, with noctua NF-A9x14 fan @ full speed
2nd setup : After I build my
NANO² setup, I recycled id-cooling IS-VC45 on my core i7 4770K...where results were not as good as on core i7 6700K (same thermal paste)
As it's in a node 202, I put a full size NF-A9 (25mm) PWM fan on top on the is-vc45 (to improve intake)
HOWEVER, whatever I tried I was completely unable to cool my core i7 4770K stock...really strange..I even believed the cpu cooler broken. I've inquired on this issue, and as far as I've read, issue was linked to the fact that Haswell has a complete different thermal schema (smaller heat spots) that is more difficult to cool than Skylake.
Finally I decided to undervolt and underclocked it, and I reached a WHOPPY 3.1GHz @0.8v on all cores/threads all the time (almost equal one core i5 6500 frequencies..
) Power status on HWinfo refers to something like 45W on OCCT.
As this level, even on OCCT, CPU was below 60°C on load (pwm control), and fully quiet inside node 202...
To conclude, id cooling is-vc45 is, for me, a kick-ass cpu cooler (the best available for NFC S4 mini at least..
), but its performance could vary depending on the nature on the cpu to cool. For sure on Skylake cpu it's working damn well.
