my aio is being a pussy again

[aren332]

i got a 4790k oc to 4.8ghz @1.325v, cache at 4.4ghz at 1.2v, dram at 1.65v, and the other day, i was getting temps in prime 95 of max about 90c. Today, i launch it, it goes up to 100c and throttles to like 4.2ghz.

During the time between those stress tests, I have not changed any settings. for both times I was running non avx, prime95 small ffts. Restarted the pc, still get the same issue. My room ambient temp stayed the same for when i got 90c and 100c. My cpu power draw according to msi afterburner at both times was 130 max, 127w avg.

 

The cooler is fully tighten, even thermal paste spread at both times

 

Ive had this happen to me before

 

My cpu is delidded with arctic mx-4 thermal paste

my cooler is a arctic liquid freezer ii 280 front mounted

 

Any fix or reasons for this?

First thing I would suspect is the pump. Has it gone bad? is the speed too low? Is there a trapped air bubble?

i bought the aio 2 weeks ago, i can hear the water flow just as fast as before

What was the cause then?

reseating the aio, but I dont think this is the current issue since after just 2 days, nothing to it could have changed

You are running p95 at a static 4800MHz.. its gonna get warm. I got the same temps on my 3770K at 4700MHz 1.36v with a Le Grand Macho RT and TY-143.

Between the IHS and CPU die or between the IHS and cooler cold plate?

^^^ Also this, P95 smallFFT is no joke, it will pull some obscene numbers. You can run ASUS Realbench if you want a similarly beefy but less intense load.

It ran before perfectly fine at the same settings at 4800mhz, now it goes up to like 87c trying to open a game

Thermal paste isn't great for CPU Die -> IHS, that's typically why people delid to begin with, in order to replace the original thermal paste with liquid metal. Given that + the load the temps don't sound too crazy. A little high for that voltage, I've run soldered chips at far higher voltages and similar clocks (4.7GHz) with much lower temps, but A) solder is better than most TIM and B) they were HEDT chips with a larger IHS and CPU die, and thus a lot more surface area to get heat out through.

what i dont get is why did it used to run prime95 at 90c and all of a sudden, it runs 100c and throttles to 4.2ghz. 90c had the same exact settings, delidded, even thermal paste spread, same voltage and freq.

Try Linpack Xtreme 1.15, you can get it at TPU. 

 

Select the stress test, select the 10GB load, and let it run as many times as you want.. it will pull all the power you have allowed.

That is not the problem, my cpu temps used to be 90 now they are 100c and throttling for no reason. Any fix? I dont care about any stress test, my cpu temps overall just got much higher like 15c, it goes up to like 90c opening games

Start over again. Take the lid off your CPU and do it over.

What is between the cores and the heat spreder? Mx 4?

No, this isn't a thing.  You don't measure an AIO by its "sound of water movement".

This.

 

And your title...  Don't go blaming an AIO for a 10 year old CPU sucking ass.

 

[RevGAM]

As @freeagent said, redo your CPU and the AIO TIM. It may have pumped out, or something else.

I just did that, no change in temps, still throttles just as much, even thermal paste spread between aio and ihs

 

In cinebench r23 it throttles to like 3.8ghz just like it did before.

 

when i took the lid off the cpu, the thermal paste on the die was spread unevenly. The middle of the die, had very little thermal paste, only the sides had some. So i dropped some thermal paste in the middle, put the lid back on, put the aio back on, but temps didnt change.

I can feel the aio pump, the tubes are vibrating for sure

Could this be because I tightened the cooler too much? I didnt tighten it that hard tho, I tightened it until i started feeling resistance.

 

Also I have a delidded i5 4570 which i practiced delidding before doing my 4790k, and I squeezed it as hard as I could with my fingers, but thermal paste spread on the die, after taking the lid off was even

How MUCH resistance?

finger tight

I also cleared cmos, just in case, still the same temps, and then applied the settings I had before:

core 1 - 48

core 2 - 48

core 3 - 47

core 4 - 46

cache - 44

core voltage - 1,325

cache voltage - 1,200

dram freq - 2133mhz

dram voltage - 1,650

dram timings - 11-11-11-30

Tighten it all the way?

 

Why would you tighten only finger tight, that makes no sense to me. You need pressure, that is why it is called mounting pressure.

With this mounting kit, not sure it makes a difference thermally because it's hard mounted. If it was a Galahad 240, or some other cooler with a mounting kit with springs to provide tension, that would definitely make a difference, but here? Finger tight could actually be good enough, but it's also subjective. With the OP stating that they turned it until they felt resistance, that's very subjective, and we have no idea what "resistance" is defined as here.
