Terribad temps on Devil's Canyon

[Ratheon]

 

 Hello there, how ya all doing?

 

 I was wpndering if anyone could confirm a hypothesis I have over a conundrum involving a very warm devil...

 

 See, about 3 years back, I bought a bundle with an ASUS Maximus VII Ranger and an i7 4790k.

 

 All well and good, but after setupI decided to run the usual tests, set my bclock to 100, static mults to 40x and disabled all auto voltage and freq controls like speedstep etc.

 

 I ran AIDA and Prime95 Blend tests, and holy crap I'm throttling at 99c...

 

 I figured that it was the crappy stock cooler, and so promptly went out and got me a Corsair h100i gtx, some coolermaster grease and set to work.

 

 Lo and beholed, thermals went from 66c idle to.

.. 50c.

 

 Ok, not quite fresh, but workable. Still, after any stress test at 1.1v+ I would hit 99c after a few mins.

 

 I reseated the coldplate several times. 2 were just bad seats, with idle temps at 89c. The rest were good contacts but still no lower than 47c idle, so within margin of error.

 

 I recently read up on the solder issues with that line of intel cpus, and so Just got done delidding and applying Grizzly LM... and it dropped a whopping... 5c.

 

 Seriously, at this point I think I just got fked over by the silicon lottery. Might as well buy another cpu

..

 

 Is that a fair assessment?

I have a TON of cooling success with that AIO.  My FX 8350 stays around 40-45c during 2 hour plus gaming sessions.  That's the only opinion I can give, that cooler is a beast and with Corsair Link...you should be able to keep that CPU cold with performance settings.  I run quiet settings and it just doesn't get hot.

You can drop the voltage like crazy on a 4790k try a mild overclock of 4.5 on all cores and 1.25 volts or so, and try to get as low as possible with voltage until you're satisfied with temps.

 I'm currently locked in at 1.183v, running stable at a fixed 4.4ghz.

 

 Still getting to throttle on Prime. Gaming and ther applications never go above 85c tho.

 

 If I ndervolt anymore it crashes under load

In that case, it almost sounds like something is wrong with the cooler, since at 1.18 volts temps should be excellent. I used a hyper 212 Evo to overclock my 4790k, so your extreme OC measures should deliver quite the thermal performance.

Exaclty what I thought.

 

 I reapplied Liquid Metal to the die, this time more generously. Same results. The delid is not the issue, it's something with the cooler or the chip itself is a garbage roll. Pump runs fine at 3000rpm. The fans also operate normally, and I can feel the pipes get prettt warm pretty quick. 

 

 I'm thinking I may have bought a mini oven instead of a cpu...

 

  As a side note, Monster Hunter World seems to hit 95% usage commonly, and is the only game that gives me temps in the 80s and 90s. No throttling tho. Wonder why its so cpu-heavy.

 

 I must say I'm quite dissapointed with this processor. It' predecessor was a second gen i5 that hit almost 25% oc at sub 80c with less cooling...
