Looking to cool i7 4790k.
At 1.26 vlts.46 mhz on all cores this thing reaches 95C on aida system test and gives BSOD 124. Don' really believe it needs volts as much as it nedds to be cooled so what I am asking is this much rad plus block adequate for cpu or do I need new block or rad ? This has treated me well up to now .or maybe I should just delid and be done with this problem. What do you think would be best solution.

At 4.6GHz with 1.26v, your CPU should be using around 120 watts of power, meaning 120 watts of heat. A single 'double' rad should take care of that no problem, much less two triple rads. While the Swiftech GTZ is an older CPU block, it still performs within 5C or so of newer, better blocks.

My 2600K is at 4.8GHz with 1.4v, which is around 170 watts. I have two Swiftech triple radiators, and I'm also cooling a GTX 780 in the same loop, and 100% load is around 65C.

I'm pretty sure that your issue is the glue holding the IHS down, the layer is probably a little too thick. Delidding might be your only issue.

Is 1.26v set in your BIOS or is it what you're reading during full load?
 
+1 for delidding or lower your OC expectations. Modern CPU do not need gigantic radiators, whose purpose is better used serving GPUs.
 
Are you currently running 2x 360mm radiators and an Apogee GTZ? Or is this what your looking to upgrade to?
 
You have more cooling power than you need. Leads me to believe its a lid problem, i'd look at a De-lid if possible. Or a bad mount on the CPU block.
 
I would rule out everything else before I would delid an intel CPU. That's very unlikely to be the problem. And if you do delid, Im pretty sure you have to remove the cpu motherboard bracket , then you need some kind of special mounting kit (i think EK makes one for their blocks) with shorter mounting screws so that you wont crush the cores with the normal mounting screws.
 
I would still agree with sok0 in the "Do De-Lid last" group ... If you can get temps manageable without delidding you are better off, however short of a horrendous mount, its probably the TIM between the die and IHS that is shit in this case, and needs either replacing (Or remove the IHS)

Intel uses pretty stellar thermal paste, it is (and has always been) the gap between the IHS and die caused by the glue used to hold them together.

While I agree that it should be the last option, it is probably the culprit.
 
Just going to join the choir on this one. You will probably have to delid or give up your overclock. It doesn't matter how much cooling capacity you have if you don't have a good connection to the heat source.

It's like putting an ice cube next to a hot oven and expecting it to be cool to the touch.

That said, anyone suggesting a delid is also doing so under the impression that you have taken the standard steps of ensuring good contact, good water flow, good air flow, etc...
 
have re-mounted several times and when removed block both block & cpu showed good spread pattern. thought about just sending it in for RMA but 4.5@1.22 and 46@1.26 seemed worth saving so I'll probably delid uusing vise method.L delid I did was Last delid I did was 3570k with razor but I have screwed up too using that method and vise method seems safer.
