custom water cooler 6700k.......

custom water cooled 6700k.......

might be over worrying here but I just upgraded to a 6700k and whilst shooting ppl in the head on BF4 I noticed it seemed to be running a tad warm for my likes. Idles around 29-34c load has been upwards of 68-72c. I thought it'd be better with a custom loop.

The Parts
Asus Z170-A
6700K
16Gb Kingston Savage DDR4 2400
EVGA Titan X (non Pascal) Hydro Copper (with EK Copper Acetyl Block) The stock Hydro Copper started flaking.
Undisclosed case as y'all may think lower of me but it''l handle several rads easily up to 480's
2 Alphacool Cross flow 360 x 60mm rads in pull (can add push if needed) I had 3 in when I was rocking my Titan X sli so I have another on hand. As well as a Alphacool 280 x 45mm rad.
Aerocool dead Silent 120mm Fans are what I wanted for the ascetic.

I have room to add the 360 back in or the 280 (and have the fans for them) but really not sure if adding it back in will give the desired results of lowering the temps to what I had on my 4930K. Which was 28/45. I have already reseated the cpu block which is a EK Supremacy Evo CSQ Copper Acetyl that did shave off 5c on my load temp I did not find any thing wrong with the first mounting so I added a small washer to each hold down to increase clamping pressure a tad. Case is setup with the 2 360's in the roof exhausting for intake I have 2 120mm front and a 140mm rear fan (might not be giving enough air to the exhaust??

what do y'all think would it be worthwhile to tear down and add in the 3rd 360 x 60mm rad??

Youre getting 72C with a 6700K on water? What volts?

Can you post a pic?

 

[S_I_N]

I set it for a steady 1.25 volts with a mild 4.3 oc havent really spent alot of fine tuning time on the oc yet tinkered with it for a while yesterday and then decided it was time to cap some foos in BF4 before bed. this was with a 15min run of Asus Real Bench

 

[tinytomlogan]

Have you got all of the air out of the system?

By a photo I meant of the rig tbh

I didnt have to drain and refill the loop I was able to move the blocks and gpu aside enough to work around (one of the joys of a removable mobo tray).
so yeah I'm 99.9% certain the airs all out. Since my 4930K ran cool with it.

I see what ur doing there LMAO ur trying to see my undisclosed case its not all tidied up yet still have cable management to do as I did alot of ssd/hdd changes as well. And as its a cube style case tubing and cable management are a challenge. Specially with these cross flow rads

 

[tinytomlogan]

It was so I can see if there is anything wrong. You may still have air in the loop or something.

 

[S_I_N]

I know just yanking ur chain let me get some current pics the ones I have are from the 4930K titan sli I tried to pm ya the case but it didnt show it went thru.










seriously concidering delidding it I had great success with my 4770K

I'm not sure if you have checked it, but the first thing I'd be checking is the cpu block contact/thermal paste spreading. It might just be a poor/incomplete contact.

I would also remove the overclock and get it all right art stock volts first. That way you know the cooling is right before you overclock (it also helps you know where your thermal limits are).

been there done that lol I'm seriously considering delidding it as I've read lot of good results

Whoops. Missed that bit. Sorry.

Delidding might work well, but if you mess it up, you better be able to replace it, as there is no warranty on that bad boy anymore.

 

[S_I_N]

its all good it was a long first post. Right now I'm debating tearing my loop down doing a flush and fill even though I just did it like 2 months ago when I sold one of my titan x's Mainly due to the gpu location on the mobo my old board it was the top most slot being an extreme board. The new one it sits like 2 slots lower and did put a kink in the tbing but I was able to rotate the fitting and slide the rad enough to fix that easily. But I'm also not overly happy with the long tube runs in the pics I like em shorter but it did help in the mobo proc swap a couple days ago. And while I'm at it I'll delid I did it on my 4770K and had good results as well.

Though it is rare I have seen issues like this with Skylake CPUs. Where they are just absolute stinkers. I think delidding may improve matters though, and I think you can get a 3d printed tool these days that does it easily and safely.

 

[S_I_N]

Yeah saw that while researching but unfortunately no access to a 3D printer going to use the razor blade method

 

[S_I_N]

after delid shaved off 5c not bad I guess. Think I'll order some CLU and redo it just used mx4 I had on hand.

 

[Warchild]

While I love delidding, I advise against doing it for Skylake. the pcb is thinner for one. Also this seems to be a issue elsewhere, delidding won't help as much as you would hope.

I see you have your GPU vertical. This is often a perfect spot for air to get trapped. Also I strongly advise you to take your loop apart and clean the blocks. Open them up and run a razor blade between the CPU fins inside the block

your temps make me think of air trapped, exactly as TTL has said. That being said, perhaps i missed it but how low do you have your fans ? I always found battlefield (especially at 120hz refresh) to run the pc warm but never that warm under water. Mine tops out at around 59C and thats with 2 gpus, and 2 rads (360 and 240). What pwm is your pump set at?

 

[S_I_N]

thanks for the reply warchild, my loop was just apart 2 months ago for the described cleaning and flushing. My temps with the prior cpu 4930K @4.5 with 1.35 vcore were great 28idle 45load while playing BF4 I did not have to tear down my loop to do the mobo/cpu swap so not sure where air could of gotten in at this point but I do agree something my be amiss.

My fans are setup as follows 2 120mm front 1 140mm rear set for intake. The rad fans are on top of my rads for pull as exhaust total of 6 120mm fans there.

My gpu temps have never been an issue before but the warmer water has caused them to spike a bit as well. But not as high as the cpu has gone.

I have already dilidded the cpu and yes yikes that pcb is scary thin. I'm going to do a tear down of my loop and check for obstructions once my CLU arrives at which time we shall see if any debris has cause an obstruction which I doubt but is possible.

if your loop was taken apart recently e.g. 2months, this could be exactly when you had some foreign object introduced into the loop or some kind of blockage especially when filling it, if you used a syringe for example and there is debris which you sucked up with the coolant.

With temps like that, I think its a good idea to just do a total clean up. Open up all blocks and clean them with a cotton bud (i use it to soak up and collect any lint or debris), razor blade through all fins, polish/clean the inside of the acetal, if needed replace any tubing or hosing with a fresh one. I put my reservoirs in the dishwasher even. Take the pump top off and clean out anything there. I do it every few months but I never replace the coolant. Its served me well for a long time now.

Also I flush my rads and run water down between the fins to remove any dust particle buildups. To me its all worth it in the end since I love watercooling.

 

[S_I_N]

I love it too been doing it for decades back when we used heater cores for rads. Well tore it all down and as suspected no blockages or debris found anywhere I checked my delid paste and it looked fine as well. Currently re plumbing with the third 360 back in also taking out my dual bay Rez and putting my tube Rez back in the water will flow thru all 3 rads before hitting the CPU block then out CPU to gpu back to Rez prolly should put a rad between the blocks but this way the tubing runs are a tad prettier. Not really cause it is a cube case there's still 2 long runs

 

[Warchild]

Will be interesting to know the result. I always like troubleshooting watercooling.

After my comments to you i went back and looked at mine. Ive noticed my mobo may have issues with pwn as the pump behaviour is acting quite odd and fluctuating instead of a fixed pwm. Maybe its on its way out after 3 years of good service but who knows.

 

[S_I_N]

Well the results are not as good as I had wished during another stress run I did drop to 63 max on hottest core gaming I stayed under 55 gpu stayed under 46 so overall it's better I just got a hot chip unfortunately. I should mention this is with fans not going over 75% I want quiet
