Another 3930k Temp Conundrum

post #1 of 40
Thread Starter 
To start things off, Hi! Long-time lurker, first-time poster. I have figured I should call upon this wealth of knowledge to shed some light onto a puzzling situation for me. I have searched for similar build/issue but have come up empty handed after a few dozen pages of search results.

I am getting what I feel to be far too hot temps out of my new 3930k. Build and details as follows :

3930k, oc'd to 4.6Ghz @ 1.375v, auto LLC.
64Gb G.Skill Ripjaw Z @ pc1600
Asus Rampage IV Extreme
2x MSI 680 Lightnings.

Cooling :
XSPC Raystorm block
XSPC Rx360 Rad - pull, top of case
XSPC EX240 Rad - push pull bottom of case
D5 Varo pump/res combo
7/16x5/8 Tubing, compression fittings.
Distilled water with silver kill coil
Order : res/pump -> Ex240 -> CPU -> RX360 -> res/pump
Currently only cooling CPU (Ek needs to hurry up with 680 lightning blocks....)

TIM's tried :
AS5, ICD7, MX-4, PK-1.

Configuration :




Temp Screen Shot :





After a burn test using p95 blend I am hovering around 75c average topping out at 79c and sometimes 80c. I have tried lowering the voltage, but after blend testing for an hour or two it'll blue-screen showing error 101. It's a C2 stepping chip. I primarily use this as a 3D workstation rendering and video editing, as well as my personal gaming machine. I figured stepping up to full custom loop away from my h100 would have served me leaps and bounds in temperature stability but so far it hasn't?!?

Troubleshooting done so far :
-4 different types of TIM, all within 1c of each other, did multiple seats to check the spread of each, getting full IHS cover.
-Disassembled system and made sure to FULLY bleed system (took 2 days of rocking case/inverting radiators etc.)
-Opened up case side and put box-fan blowing into case, temps only dropped 5c or so.
-Double checked my waterblocks in/out flow was correct.


This is very frustrating as I have spent $$$ for a relatively negligible gain over my previous h100 mad.gif. Any advice from all of the Guru's out there??

What am I missing?

Ambients?

And how does your blocks base look? There are a plethora of people that have non-flat raystorm base plates.

What fans are you using?

Ambient temps hover between 23c and 26c,

Block was pretty damn flat with a mild covex bow at the center. TIM spreads don't show an excessive amount around edges of IHS.

Fans throughout are Aerocool shark's, ran about 1000-1200rpm.

Fans, especially at those speeds have very low static pressure...that in combination with the bow I'd say that explains at least a few degrees if not a bit more.

What fans would you recommend to replace with? From reviews I've seen the sharks hold their own with SP specs.
post #6 of 40
At full boar, they have less static pressure than the SP120 quiet editions... fan recommendations would be solely based on what you want out of it. People love the GTs, some love the SPs, some love yates, some love deltas, etc etc

I guess another question I should ask is what temps you were expecting.

I personally think those temps may be a tad high as well. But probably not by as much as you may think.

I have a C1 stepping that needs 1.37v to run @ 4.5ghz. So pretty similar to yours. At this speed and voltage my temps get to around 74c with an ambient temp of roughly 20c. Again pretty similar when you take the delta between our ambient and max temps into consideration. The big difference though is that I have one TFC xchanger 360 rad cooling my CPU and my 7970. You have two rads cooling just your CPU. I also have a RASA which is very similar to the Raystorm.

Now I know all chips are different but I considered mine to be below average for voltage requirements and heat output. Plus yours is a C2 stepping which from what I have seen seem to generally better than the C1 for volts and heat. Not all of them though. Just on the whole.

Could just be the luck of the draw on the silicon lottery but I hope I am wrong and there is something that maybe you have missed. Is your pump speed set to max, did you clean out your rads before using them as some can come blocked up with gunk, deafboys comments, loop order (I personally don't think this one should make much difference if any but others claim to have noticeable results doing it one way or another). Any one of these may not make much difference but all together could be quite a large gain.

Now as for the bowed block I have known this could be an issue with mine for quite some time now. I just haven't got round to checking whether it is bowed. I personally am waiting on a switch 810 before I remove it again as I am going to introduce another TFC 240 rad to the loop and lap my RASA whether it is visually bowed or not. Jut to be sure. It may be a while before I can produce results but I'll be sure to let you know what they are when i have them.

Raystorm actually has more of an extreme bow, and not mild. It looks like a contact issue, you have 1 or 2 cores with decent temps and they get worse moving away from those two.


You have badly matched rads. The RX loses steam around 1500rpm, and the EX is just waking up at 1500rpm. I might get some AP29's and run 'em at 1k rpm, and turn it up for silly static pressure when you need it.

Call me an optimist, but was hoping for That much rad-space being able to handle 1.4v worth of heat (whether it be 4.6 or 4.7 max clock speed) at mid 60s peaking to 70 or less.

Guess It's time to shell out for some GT's... or some Swiftech Helices since they are roughly half the price. Possibly a different waterblock too. or just lap my raystorm.
