1950X High temps - could my CPU cooler have an issue

Noctua make 3 coolers specifically for Threadripper; NH-U14S TR4-SP3, smaller NH-U12S TR4-SP3 and smaller still NH-U9 TR4-SP3.
If I was building a Threadripper I would most likely use NH-U14S TR4-SP3. :D

You ordered Enermax Liqtech TR4 360? Look forward to hearing how it works. :)
 
I have the Enermax 240 now that's whats causing the problems - no idea on the cooling potential but thats probably why its been so noisy.
Its very loud and has been very sensitive with the fans revving up really quickly - all makes sense to me now ....
 
With Enermax has at least 3 different lines of CLCs I don't know which one you have.

Their Liqtech TR4 pump is rated 450 l/h. They don't say what their other pump flowrates are. ;)
 
Its the one for then Threadripper OC only sell 3 models is the 2 x 120mm one with the full coverage block LiqTech I think - rated to 500w TDP.
I like it, I am gutted for all the grief
 
I would guess the 360mm radiator will cool 3-5c better than 240mm radiator.

Reviiews I've read indicate it is decent with much lower temps than U14S .. and quieter at full load as well, don't know about idle pump noise.
Am interested in how it all turns out.
 
Overlockers have rejected my request for a Refund which I am pretty peed off about - Bad Customer Service in this instance.

I understand how things work and that they should be allowed to check the product and provide a replacement which in 99% of cases I would be more than happy with.

However when a product is essential and you cannot use a computer without it - and you need that computer for work, you cant earn your living without it - and are therefore forced to buy a second unit as you cant afford PC downtime, let alone the weeks of RMA time, this is not a normal siuation.

But Overclockers are happy as they make twice their profit from you in this instance.

I didnt know the product was faulty because I didnt stress the pc in the first 30 days to know - for products like this there should be seperate RMA Guidelines.

Overclockers dont lose out - they ship back to Enermax and have their stock replenished with a replacement unit.

As it stands they make 2 lots of profit and appear as Greedy to the unlucky customer who has spent their hard earned money with them for years and has all the grief of replacing a CPU cooler so has to go through all the cleaning and installation process with the risks attached.

Its unfair and unreasonable business practice and how you lose customers - I am pretty peed off today actually and had I received the email reply from them sooner I would not have spent more money with them today as I have. Most disappointing
 
Today is a new day

Installed the Enermax LiqTech 360 shortly ago - straight away idle temps in the 20's not high 30's as they was this morning with the faulty Liqtech 240.

I blasted out some cpu rendering with the very low vcore settings I have got the cpu on because of the faulty cooler - temps low 50s now, this morning with the faulty cooler was in the 80's in seconds.

Heres hoping this lasts and no more faults with this unit.
 
When I took it out I could hear gurgles as I moved it about - I dont know if that is a sign of an airlock or something but either way the whole purpose of these units are they plug and play.

Still very annoyed by the whole situation - it was working but poorly as to even a fairly experienced user, but one who had never used a so called very hot cpu before didnt notice for 4 months. Then is stuck having to buy a second unit.

Leaves sour taste
 
4Ghz 1.325v Low fan speed idling at 26c thats pretty impressive and more like what you expect for the money - just in case anyone is interested in the LiqTech 360 for Threadripper - when it works, its great

While that may be the assumed 'whole purpose of these units' the reality is air bubbles / air locks are part of water cooling and have to be dealt with to one extent or another in all liquid cooling systems.

Sorry, but nothing is 'idiot proof' and you are no idiot so you know it's part of dealing with water cooling.
 
Agreed - but a user of such a unit cant be expected to keep disassembling the unit to move the water around in the loop - that is what the pump is for.

the 240 has been faulty from day 1. I had it originally mounted to the top of the case - but had really high temps - associated I thought with the 1950x so I changed the installation to be front mounted to have clearance for push pull fans and cold air intake from outside the case.

This cooler I ave installed the same and temps not above 66c so far at 100% - I have done nothing different and am seeing 20-30c + differences in temps at higher vcore and load.

Thats why I am frustrated because I associated the high temps with the wrong thing and dont really push the cpu very hard very often to notice. It should have been pulled out straight away
 
I understand your frustration, but in reality it often takes more then one juggling positions of loop to get all the air to top in radiator. It takes time for all of the very small particle/air bubbles entrapped in water to separate. Before I mount and after mounting AIO/CLC I move them in different positions while running to get all air entrapment moved to highest point of system and of course mount system so that point cannot create an airblock/lock and restrict/stop flowrate.

If it was it really 'faulty from day 1' my guess is it was air bubbles creating a partial airlock. This is the sort of problems that are part of dealing with water cooling. If you don't want to learn about what they are and how to resolve them then you should probably not use water cooling. I did custom loops before we had custom loop components and continued using water for many years until 2005 when high performance heatpipe air coolers (Thermalright Ultra 120) became available.

Again, I understand your frustration. I'm only trying to explain how if you continue to use water cooling you can avoid similar problems in the future. That or change back to top tier air cooling and optimize case airflow. ;)

1950X is 180TDP and while that is high for a stock CPU, there are many air coolers that can easily cool 340TDP with proper case airflow. Some will cool even more. Anandtech reviews test from 60w, 100w, 150w, 200w, 250w and 340w with 10 air coolers cooling from 28.8 to 40.8c delta, so add 22-25c to that for cooler intake air temp and we have 50.8c to 65.8c CPU temp. Even Evo 212 does a 54.9c delta @ 340w .. that would be 79.9c with cooling intake air at 25c.

My last proper build was a full waterloop - and was fully up for all the effort that is required to use it. You dont buy an AIO for hassle - you build your own loop for hassle.

In the instruction manual for the Enermax there is no mention of maintenance, installation practices, post installation move it around that I have seen. I did read it more closely this time around to see if I made any mistakes, but I didnt. They are designed to be simple and easy

The last AIO I had one of the first Corsairs, I installed that and it worked perfectly without any maintenance - that was years ago.

It should have just worked and I was open for it being me doing something wrong - but after I powered it directly from molex, moved the case around and was getting cpu throttling on low vcore that was the final straw. It would be for you as well I am sure.
 
I guess it's a case of 'buyer beware' because air bubble / air lock/flow restriction is a common problem with AIOs/CLCs. Reality is the are designed to be able to build at very low cost and to sell, as in fancy trim, LED lighting, etc. The whole marketing ploy is based on the premise of 'water cooling' and that people fall for the assumption that if it's 'water cooled' it cools like custom loops even though custom loops cost many times more.

Reality is top tier air cooling is as good as CLCs running at same noise levels or very close to as good against CLCs like yours now is. I have tested many air, AIO and CLC coolers and with similar noise level high performance fans most top tear air coolers are several degrees better. Only exception I can say for a fact is as good is Swiftech, but maybe Liqtech TR4 280 and 360 might be as well.

It is possible your 240 has a pump problem or other flow restriction that is not an air lock. Obviously we can't troubleshoot it without hands on use o
and even then it might need to be opened up to verify it's a pump problem versus a blockage somewhere that is restricting it's flow.

If you ever want to go back to air cooling I would be glad to help you setup a good system. I have an old i7 920 I can run at 4.3Ghz and stay below 70c on air. I run it at 4.0Ghz to be below 65c. ;)

I'm also running i7 980 and 6700K but they are running stock setting because for my use they are plenty fast.
