What's a good fan to go with it and something which isn't noisy?
I heard Panaflo is good but anything else?

It's pretty hard to tell how flat it is from our eyes but yes, some of them aren't flat - like our CPU's

Liuteva, according to some owners, it wouldn't and this cooler only weights about 0.8kg despite being large in size.

I believe both fans are pushing out to the rear exhaust fan of the casing? This should work well?

Thanks I'd certainly like to try the IFX out someday.
Anyone changed from GeminII to this and what's the gain like?

That's a very good improvement, something similar to a basic WC setup.

Does anyone knows if the whole HSF including the back panel can fit on the Cooler Master 690 casing?

Thanks. I think the height shuold be ok but the extended one at the back is my worry.

I wonder if anyone tried Ultra Extreme VS IFX-14? Real life experience and not from the review sites because it says both are identical.

I'm thinking of getting this very soon

IFX-14 for RM290 in Low Yat
Ok, I've just got myself the IFX-14 and for those who wants to use it with smaller casing, beware. The size is huge (I knew that anyway) and it fits very tightly onto my CM690. No extra spaces in between and it's so difficult to mount the motherboard. The back side heatsink totally does not fit (Maybe I can sell it to Ultra Extreme owners).

The first thing I did was to lap the IFX-14 and you need plenty of sandpaper to get the job done (imagine it). The base is so uneven that I can't even believe it for a RM300 HSF (sad but true). Here's a pic of it inside my CM690:



First look and thoughts between GeminII and IFX-14
Idle temp differences are minimal, around 3C-4C and it takes a lot more space than the GeminII which makes life a bit more difficult to mount on a small casing (like mine). However if you're a heavy overclocker which tends to pump plenty of voltage then this is the HSF for you. The IFX-14 is capable of handling the load temps very well and despite 1.43V, it manages to keep my temps at 55C-57C which the GeminII isn't capable of.

For those which does mild overclocking, you can save your time and buy a GeminII unless you want to spend an extra RM180 to see a 3C-4C drop in temps which is pretty pointless IMHO since you don't need it.

Unfortunately I'm someone that doesn't like to lie or tell myths. I tell everything based on true facts and experiences plus I don't defend something just because it's expensive As a conclusion, I personally think the IFX-14 is a good cooler and beats the GeminII under certain conditions but not to the extent that it's tremendously superb for the price you pay.

Thanks Quazacolt. It's meant to tell others not to expect so much if they plan to get IFX-14. Your casing would be able to fit the IFX-14 and very likely including the back heat sink.

allenultra, if we're talking about 1.43V, the IFX-14 is better by 4C-5C compared to GeminII. I tried pumping 1.45V and it already hit 60C-62C full load Orthos.

Of course a more precise comparison would be to see the heat dissipation at that clock speed as heat dissipation vs voltage increase isn't always linear. The sad thing is, I've no idea how to get the wattage produced at that speed

Extra RM180 bucks for +/- 5C difference is a bit too small IMHO

mADmAN, the Ultra Extreme has a much better and flatter base. Your explanation has some valid points too and I agree the IHS is not flat (corners tend to be thicker). However if you see the IFX-14 and put it on a glass surface, you can move it left/right (very uneven).

I think you can just use as it is. If the temp is terribly wrong then you can consider lapping.

LOL, true also. I did not try it in the original state cos I went straight to lapping. In fact, most people would just mount as it is. If you have a very flat surface (marble, glass, etc) then you won't go wrong or make it uneven.

How about going for the Ultra Extreme?

You need plenty of sand paper as it's very uneven
I'm not sure how it can damage the IHS plus the mounting is via screws so you can always control the pressure. I'm sure all of us are smart enough not to tighten the screw further if we know it's too tight, etc.

The extra passive cooling does not fit on the CM690

I've never used the back passive cooler throughout my ownership of the IFX-14. In actual fact, it's quite hard to get a casing that lets you fit the back part without "modifications"

I'm not sure why they designed it that way but the IFX-14 is really a pretty good cooler The best air cooling so far until something better comes around, lol.
