Hello world!

This is my 1st post, however I was a regular reader since 2017r.
As my old AIO died after about 6 years I've decided to go custom loop with hope that my old system performance can be increased, previously limited by temps.
According to EKWB configurator sufficient radiators were 1x240 SE + 1x240 PE - setup limited by my current case which is Corsair 350D.
However I've modified it to make rad config futureproof. Now I've got 1x 360 PE at front with 2 fans (3rd one will not fit) + 1x 240 PE at top with 2 fans. Front fans pushing air into the case, top extracting it outside. Fans I'm using at the moment are old 2x Corsair RWF0016 PWM at front, 2x LED Corsair AF120 3pin at top.

Whole system summary:
Rad 1: EK Coolstram 360 PE with 2x Corsair RWF0016 PWM fans - new rad, my old fans
Rad 2: EK Coolstram 240 PE with 2x Corsair AF120 3pin fans - new rad, my old fans
CPU Block: EK Supermacy EVO X99 - bought used
GPU Block: 2080 Vector Block + Backplate - new
Pump: Aquacomputer D5 NEXT - used
Res: EK Res X3 150 - new
EK Hardtubes and fittings 12/10mm

CPU: Intel Xeon E5-1680 V3, which is basically i7 5960x (8C/16T). Overclocked to 4.5GHz @1.3V. Power draw is 270W
GPU: Reference design RTX 2080 non OC version. Overclocked to 2050MHz @1.000V + 15400 Memory. Power draw 240W
MOBO: ASUS X99-M WS/SE
RAM: Quad channel 32GB RIMM 3200MHz 15/17/16/36 1T

Now the problem - temperatures:
CPU with normal usage reaches 70°C, while testing in AIDA it reaches high 80°C
GPU pushed to its limit can go up to 60°C. After 15min of 3dmark firestrike ultra stress test coolant temperature reaches 40°C, so that means it is absorbing the heat. System is stable, but at canstant raising temps not for long I guess

Concerns:
According to EKWB config that amount of rads should be sufficient to keep coolant temp ar 31°C, but somehow it is not the case
Are the problem is fan setup? Airflow at front is limited, just 2 fans are used (3rd one wont fit) and solid cover, air should be sucked through small gap on sides/bottom. Also I'm not sure if those fans are good and maybe replacing them solve the problem?
I'm not sure if CPU temp is fine, wherever I look it should be below 70 at stress test which is not the case for me. As a comparsion my old AIO corsair H100 was able to cool CPU to similar temperatures but at 4.4GHz @1.240V. It was throttling at current WC settings straight away.

In future I'm planning to change the case for Lian Li o11 EVO announced recently. But still want to keep current setup as it is capable to my needs.

Thanks for reading, suggestion
and have a good day :)


BTW. Can I attach picture here or it have to be a link?
 
Thanks for quick answer.
Yes, in EKWB configurator I've selected quiet overclocking. According to it 2x 240 SE + PE rads should deal with 510W @31°C, I've got 360 PE and 240 PE so that would be considerable more.
Fans are driven by D5 NEXT pump, at coolant temp over 35°C pump and fans are set to max speed.
I think that heat spreader is non removable on those CPU (soldered?)
I need to do more testing now as I've put everything together just 2 days ago. I suspected small case and poor air supply issues there (fans). I'll do some study there as well.
Any fan recommendations? Do not need rgb, just performance.

For CPU and GPU I've used a thermal paste provided with GPU Block, some EKWB branded one.

UPDATE:
After some digging Ive replaced both AF120 fans with ML120 ones, both from corsair. According to manufacturer static pressure is much better on ML series. Now I can feel the air coming from the top of the case, mentioned before 3dmark stress test is passing without problems and water temp is up to 32°, gpu just over 50° and CPU mid 60°. And everything without pump/fan on full speed, which is a huge improvement. However CPU stress test is still mid-top 80°. Looks like I have to live with that.
Did not realised that fans could make so much difference here. Up to now fan was just a fan...

Thanks for tips guys.

I've tweaked and tested the setup a bit more now, been able to get even more performance from RTX (core 2085MHz @1.000v, 2000MHz (total 16000MHz) for memory. GPU temp reaching up to 52°C, Hot spot temp, which seems to be equal to memory temp reaching up to 67°C. CPU temps in normal tasks is acceptable as well. But all that without front panel, with it is completely different story. As SS-89 mentioned lack of 3rd fan on 360 radiator and poor (or close to none) airflow with front panel on is a problem here. I guess that extra Delta fan would fix that permanently, but I'm trying to make the setup silent as well :)
I'm not a fan of huge cases and Christmas tree look, so need to figure it out the best solution - probably new case, as cant squeeze any more from current one.

My options are:
1. new, bit bigger case - if I find one which I like and it will squeeze current radiator setup without any sacrificies
2. new fans, but good 5 ones are probably similar priced to reasonable case
3. PWM fan controller (if my fans are really 2400rpms, need to check that), but I have no idea how to set water temp as a speed trigger. that is why fans are on pump header, not mobo headers as before


Ive got 5 of these fans https://www.custojusto.pt/lisboa/in...corsair-de-alto-desempenho-pwm-120mm-33355883, no idea if they are ML fans as Corsair have no info on their website. All coming from (i guess) my old H100i AIO and non RGB case. They suppose to be 0.3A 2400RPMs, but my aquacomputer pump can drive them only up to 0.11A 1700RPM for some reason. I'm pretty sure that motherboard could spin them faster, as they were louder at full speed. I think that 2 fans at front spinning @2400RPM should be sufficient to keep reasonable water temps with front on. Extra option would be 3rd fan @360 Radiator (I can cut off some plastic reinforcement on case to squeeze it), but I have no idea if that would make any difference, as it would be completely cover up with 2x 5.25 bay covers - no air to draw from.

Before I started I knew that with that case might be some performance issues, just didn't except them. Case now is so heavily modified, that it is not sellable anyway. I've run ekwb configurator again - it is predicted that power draw would be 580W, which is already more than my actual max. My rads are able to dispose 834W there, so a lot more than anticipated. So it is strange, that 1 missing fan on 360 rad is making so much difference. Unless they assume there, that fans would be @ full speed in open or no case - which is misleading.

MikeTimbers that phanteks case is big...

Any idea then why aquacomputer pump does not power them up @ full speed though? I've connected them one after another and all were between 1630-1720 RPM and 0.11A at max setting. Making them run faster could give me some time to find a good case deal. All interested ones are out of stock anyway...
 
All the information which I've provided in previous messages are from aqua suite. As I've mentioned after setting fan speed there for 100% power in the software it only spins @~1600RPM and draw 0.11A at 11.9V. I've got a curve setting for pump and fan speeds, they should reach their max at 35°C water temps.
I'll check today how fast they could spin at motherboard header, suspect that would be 2400RPM, as when they were connected to motherboard every PC power on cycle sounds like a launching rocket when fans were @Max for few seconds before bios setting kicked in.
 
I've tested the fans on motherboard header and they are actually 1600RPMs so my feeling was wrong. Looks like last 2 digits in their model number RWF0016 are rated speed. Without case front I'm satisfied with system thermal performance, got high 40°C on GPU, low 50°C on CPU while gaming and water temps are 31-32°. With front on everything goes by 7-8°C.
I'll leave it as it is, before summer temps with 1st coolant change I'll get new case as well, probably one of the recent Fractal Meshify ones, then fans - Noctua NF-F12 2000RPM or Corsair SP's. Just hope that after all those changes system would be cool and quiet in the same time.

Thanks all previous advices gents!
 
In the meantime I've replaced fans on 360 rad for Arctic P120 which supposed to be very good fans, and haven't noticed any difference in performance. Yes, they are quieter at 1600 rpm, but that would be it. So corsair fans were efficient enough, the rads or small case restricting airflow are the problem. All works, but not as anticipated - it should be cool and quiet, not just cool.
Just wondering when cases which I like would show in stock. There are shortages of everything these days :(
I'm after Fractal Meshify 2 or LianLi O11D. However got some doubts about 2nd one performance.
