Cooling i7-6700k delidding and cooling

I've upgraded from an i5-2500k at 4.2 (hyper 212 plus) to an i7-6700k at stock (Noctua NH-L9i).

I'm thinking about delidding and picking up a beefier cooler. I've found some delidding services on ebay but I was wondering if anyone knows of one in London that offers a reasonable price so that I don't need to pay for and wait for 2-way shipping.

What is a reasonable cooler for reaching 4.5-4.6 that is reasonably priced?
I know the Noctua NH-D15 is the best but I'm not paying £80.
I also want it to fit in SFF case when I get my HDDs sorted and finish my ITX upgrade.
Low idle noise is a priority. I don't care as much when I'm gaming as long as it is reasonable.

 

The question of frequency ultimately depends on your cooler choice. Make that choice first, and we can advise based on that.

Man... I wish I could still offer the service to you guys.

 

The default choice for cheap but good aircooling would be one of the 34688547 Coolermaster 212 variants (they are only around £25 - 35 depending on model).

Fitting it into an SFF case? That may complicate matters though depending on which case you go with as some of them only work with low profile coolers.

 

Stanley blade on each corner. 5mins max job. Less 20c temps. Easy as that........maybe

 

I don't mind seating a CPU cooler as it doesn't have any associated risk. I don't want to deal with the tapping and using a liquid metal without practice.
If I get it done, I want it don't properly.

 

A razor blade is extremely risky unless you know what you’re doing. I’ve done it a number of times, and would highly recommend against it when there are such easy to use tools around. One of my buddies killed a new 6700K because he didn’t notice the extremely small ding in the blade. He scratched the PCB and killed it outright.

 

Which is why I don't want to take the risk myself

 

Yup I killed a 3770k delidding much like that, so it goes, bought another and did it right, got me another 200Mhz at better temps, hardly worth it really, though a 3770k @ 4.9 is faster than my current Ryzen... unfortunately I also killed that chip, this time by dropping a cup of tea on my PC Doh!

 

Happy to loan you the tool to delid it if you want. Or can delid for you and apply liquid metal. My 4790k was ludicrously hot though and was able to go beyond my 4.4ghz cap up 4.8/4.9

 

That's a kind offer, I will have a think on it after I submit my dissertation.
